But ... the whole discussion (or argument) over whether it's an "edition change" is pointless. There's the actual publishing definition- which is entirely unhelpful, because no one has ever used that.
Beyond that? There has never been a single accepted and consistent use in the history of D&D for what is, or isn't, an edition change. It's literally all marketing speak. Even the "half edition" is just something that they happened to do once, because it occurred too soon for them to call it a new edition.
When people are arguing over this, they are really arguing over the underlying substance of the changes. But they are using the nomenclature of editions in order to argue this.
In the end, it doesn't matter whether or not, for marketing reasons, they decide to call this 5e24, or 5.1e, or 5.5e, or 5e Essentials, or 5e Super Errata'd, or 5e50 (for 5e 50th Anniversary), or 5e Plus Tasha's But Cleaned Up, or Advanced 5e, or BladeRunner 2049.
Instead of discussing the nomenclature of the game (which will be whatever they decide on), maybe focus on the changes? And since they've told us what they are naming it (based on the year), it really does seem strange to continue to have this discussion?
From my POV, YMMV, IMO, etc.
