There have been changes to the maps already depending which book you buy so how exactly is that "no changes"
In Eberron? I believe that was what I was talking about. No map changes that I recall. Or lore changes. Or timeline changes.
(Okay, dragonborn and eladrin were added. But that's an addition, not a change.)
In the Realms, the 5e Realms is much, much closer to the 1e/2e Realms than either the 3e or 4e Realms.
There was a post a while back that overlaid the SCAG map over the old 2e boxed set maps and they were almost identical:

If I get a 2e Planescape books and a 4e Planes book, whoops plenty of changes there.
But it changed back! So that's easy to ignore. Since we're talking about using 2e Planescape books with a modern campaign, what 4e did or did not do is irrelevant to the discussion.
Again, all the lore in the 2e books works just fine.
I could go on and on without even mentioned the actual important stuff that differentiates settings from each other but really a Warforged is just the same as a Half-Giant is the same as a Dragonborn, right?
Sure no changes, you guys crack me up.
Some worlds changed. Dragonlance for one. Events happened in the novels that were not reflected in the last published game book. But, if you're a Dragonlance fan planning in playing in that era, you likely have the novels.
You play worlds for the worlds. The setting. The place names, the type of stories you can tell, the lore and backrgound of the world. None of that changes between editions.
I used my Ravenloft books just as easily in Pathfinder and 5e as I did for 2e, because the setting itself didn't change. The fact that the fighter now gets Action Surge doesn't mean that Il Aluk is no longer the Necropolis or that Vancian casting works different doesn't change the location of the Nocturnal Sea. The setting doesn't become a hopefully happy place because the rule system is different. The stories I want to tell and the type of game that the setting works with are the important elements.
What do I need to play Ravenloft in 5e? Well, I don't *need* anything. Even if converting my old groups to 5e, none of them really happen to use any options that don't exist. It would be nice to have some rules for Powers Checks and a couple races. So 5 pages in total.
What would be a nice perk for Eberron? A handful of races and the artificer. But, again, unless you're updating an existing campaign that makes use of a warforged artificer, it's not a big deal and you can play just fine with the existing 5e content. Worst case scenario, you have the playtest of the artificer class and the
warforged (and Kobold Press have their gearforged race as an alternative).
