I'm not opposed to a date based model for "minor editions" but I don't think it's going to stick if we're still having discussions that encompass multiple editions. Frankly, "5e (2024)" or "2024 5e" is just a longer and clunkier term than 5.5, which is why my money's on that one settling down as the norm.
The thing I'm objecting to is WotC's framing that's suggesting we won't be talking about 5e 2014, and 5e 2024 as separate entities. Of course we will. Someone is going to start a thread a year two years from now saying that a 2014 rogue is like Y, and a 2024 rogue is like Z and either bemoan the change as a travesty of game design, or a brilliant innovation, and someone else will chime in that they're keeping the 2014 version in their game, and someone else will be sad they can't do the thing they used to do with their rogues, because all the DMs just use the 2024 version these days.
WotC's pushing for us to round this down closer to errata and less like 3e vs. 3.5 ranger discussions, and that's unlikely, and a little disingenuous. I don't really understand why there's a push to support that rhetoric, both because I think it's pretty pointless, and because I don't see what the benefit for anyone other than WotC's marketing push is.
