Ravenous Bugblatter Beast of Traal
I've been talking to several people in this discussion, so I don't assume that you've read everything I've written, but I have addressed this.So if WotC releases a new SRD for the 2024 version with the rule changes then 1DD and 5e are the same too? I expect that for the core rules, e.g. the different conditions etc. The classes always were meant to exist in parallel. So 1DD then is the same edition as 5e according to your own definition.
One of the points is that there are multiple criteria needed to be the same edition. One that I was focusing on, mostly because it looked like they were not going to meet it so it rendered discussion of the others moot, is the there are fully updated rules that contradict each other and the DM needs to say "we're playing with these rules, not those rules".
So nothing I am saying is "this is the only criteria to make it the same edition", it's "this is one criteria it is likely to fail that will make it a different edition".
There are SRDs out for multiple editions, so coming out with a new SRD doesn't inherently replace. And even if it does, that doesn't mean it errata's other books.
I have been talking about the published books. To expand out what I've said in several posts: if my 2014!PHB is completely up-to-date (e.g. has all errata published for it) has different rules (as in rules, not classes, spell descriptions, etc.) than a 2024!PHB that is completely up-to-date, such that the someone needs to pick one or the other as authoritative, then they are different editions.
