the whole wayland ecosystem is slowling taking shape month after month. and given the radical change that wayland is, most thing have to be re-implemented using radically different tooling, libraries and approaches, which is very similar to re-inventing.
Which is to say: what you say is true, but there's no excuse for breaking screenshots (!) for half a decade in the name of "progress".
(And I say that as someone who genuinely thinks Wayland itself is great software. But the desktop projects and distros have a job to do too, and they didn't.)
I mean, no one was surprised in 2016 when Wayland landed that there would be bumps in the road. It's 2021 now!
Breaking, or wholly removing, loved and important features because the developers believe they know better is sort of the modus operandi of the Gnome team; and don't you dare file a bug report. They don't accept criticism graciously.
See also: file picker icons, desktop icons, task tray, et cetera.
I generally parse this as half-baked, not battle-tested, and difficult to use.
