How to apply
my principles to Dragonlance. This is how I'd prefer that Crawford and the RPG Studio team approach Krynn and its Realities/Timelines:
1) Characters such as Astinus, Raistlin, Dalamar, the gods, and the High God, are aware of the existence of multiple Realities. Astinus named and catalogued these different Realities.
2) The mainline novel/fiction timeline is given a Official in-universe designation:
Krynn Timeline N (aka "Krynn-N" and "Krynn's Reality N.") Really this Reality N can span all editions (and worlds), since it includes only novels and fiction, and isn't really affected by rules lenses.
3) The rebooted campaign setting (
Astinus's Guide to Krynn, or whatever it may be called) is a distinct, named Timeline:
Krynn's Fifth Timeline (aka "Krynn-5" and "Krynn's Fifth Reality")
This Timeline is already glimpsed in the DL 5E bits we've seen so far, such as Fizban's narration of the dragon book.
4) All the divergent timelines from the River of Time sourcebook are given distinct in-universe designations. Same for any other continuity snags (large or small) which have ever been noted in any DL fiction or gamebook. These are all distinct Timelines.
5) The previous "rules lenses" of Krynn are given an in-universe designation. Because the rules changes do affect how the characters manifest. (See Bruce Heard's article about this, which I reference in "my principles" post.)
Namely:
Krynn's Third Timeline (aka "Krynn-3" and "Krynn's Third Reality"). The 3E game depiction of Krynn. Always was 3E and always will be.
Krynn's Saga Timeline (aka "Krynn-S" and "Krynn's Saga Reality"). Saga card-game depiction of Krynn. Always was depicted by the SAGA card lens, and always will be. Theoretically, there are SAGA cards for pre-SAGA and post-SAGA events and character options. They just haven't been published.
Krynn's Second Timeline (aka "Krynn-2" and "Krynn's Second Reality") Always was 2E and always will be. For example, though it was originally AD&D 1E, the War of the Lance module series was later converted into 2E. In this Reality, Krynn was always depicted in a 2E lens, and always will be. The Chaos War and War of Souls happened, but the 2E lens remained in place. Which means that the Saga-era of this Reality would be depicted with 2E version of the Mystic and Sorcerer.
Krynn's First Timeline (aka "Krynn-1" and "Krynn's First Reality"). 1E Krynn. Always 1E lens, past, present, and future. For example, 1E version of the Saga Mystic and Sorcerer. 1E version all the 2E DL Monstrous Compendium monsters. 1E version of the 3E classes and prestige classes. 1E version of the 5E classes.
Krynn's Legacy Timeline (aka "Krynn-L" and "Krynn's Legacy Reality"). Unlike the other Realities, which are depicted through a single lens (aka game system), in this Reality, Krynn's "lens" shifted in synchronization with all the "Multiverse Shattering Events" which effected (and often originated in!) the Forgotten Realms. And Krynn's timeline continued to advance year-by-year "off stage", completely in-step with the chronology of the Dale Reckoning of the Forgotten Realms. (The different length of years is taken into account some way.) Even though we rarely if ever saw Krynn in this Reality after the 3.5 era.
All the various River of Time alternate timelines will interweave with this matrix of rules-based Realities, forming a complete matrix of Timelines; only some of which have actually been seen in print.
6) Same for other DL media, to the extent that they carry a story. Such as:
-Various
Krynn-V Timelines: Category:Dragonlance video games - Wikipedia
-
Krynn-F Timeline (Animated film)
Dragonlance: Dragons of Autumn Twilight - Wikipedia
-
Krynn-CDC Timeline (Krynn's Reality CDC) DC comics series, a Reality also seen in Forgotten Realms DC comics and AD&D DC comics.
-
Krynn-CDD Timeline (Krynn's Reality CDD) Devils Due comics series.
-
Krynn-SQ Timeline (Krynn's Reality SQ). The five Super Endless Quest / Adventure Gamebooks which are set in Krynn:

Krynn-CC Timeline (Krynn's Reality CC). Catacombs maze game:

-
Krynn-BB Timeline and Krynn-BA Timeline. The Dragonlance Boardgame, which has basic rules and advanced rules:
Dragonlance
The story and visual imagery (depictions) are somewhat different in all these Realities/Timelines. Though this may seem super-completist, that's the way the Transformers Omniverse labels its "universal streams" (aka timelines). Every little variation, seen in any medium (sticker book, toy packaging, etc), written or visual, is given a distinct Timeline moniker. These monikers are used in-universe! D&D deserves that too.
7) And of course, each DM's own Dragonlance campaign is its own Timeline/Reality. This should be acknowledged as well. When DL is presumably opened to DMsGuild, aficionados will be free to publish their own Krynnish Realities commercially.

The sidebar explaining all this could be not much bigger than my post here at ENWorld. The masses (and everyone) will be happy with an awesome DL 5E reboot. And the grognards will be happy that all the Timelines have a clear place in the meta-continuity, going into the future. Which is summed up in a nice tidy sidebar or DRAGON+ article, so that gatekeeping lore isn't clogging up the gist of the reboot.
And furthermore, it leaves open the possibility for the occasional 'what-if' crossover between Timelines.
