The point is so ludicrous though.Do we count if we say it's really a half-edition?
Look, if Group A is playing with Core 5e only. So, 2014 PHB, DMG and MM. And Group B is playing with every WotC release, including things like Tasha's and Xanathar's. Are they playing the same "edition"? Really? After all, Tasha's has already updated and changed a number of spells. Xanathar's rewrote the tool system and the downtime system. We've added an entirely new class - the Artificer. Additionally, every other class has had what, half a dozen or more sub-classes added to them.
And that's not counting a bunch of new feats, new equipment, a raft of new spells. So on and so forth.
See, this is what always trips people up. If you play at the leading edge of an edition - keeping up with the latest releases and using newer material, the changes between 2014 and 2024 are pretty minor. It was a similar situation with the switch between 3e and 4e. If you played with the later era releases of 3e, 4e wasn't much of a shock at all. OTOH, 3.5 Core vs 3.5 + a bunch of releases were as far apart as any edition change, other than maybe 2e to 3e.
The idea that 2024 D&D is going to be this radical change to the game just isn't true. It's only a bit of a jump if you're still playing mostly core only 2014 D&D.
