So the largest two desktop environments defaulting to it, popular WMs (sway, etc) getting Wayland versions, PLUS agnostic projects like Firefox, is "zero momentum?" If anything, it's made (sadly) obvious which projects severely lack resources to migrate - the XFCE, enlightenment, gimp, etc. of the world.
GIMP hasn't even migrated to GTK3 yet. The upcoming GIMP 3 will finally use GTK3 and is slated for release in a few months, but this is years after almost everyone else. Certainly in the case of GIMP I think "lack of resources" can be substantiated pretty easily. IIRC GIMP 3 will also get Wayland support – I'd have to check to be sure.
I'm less sure about XFCE or Enlightenment. Judging from [1] the XFCE people have been working on it since Feb 2021 (when that page was created), but real issues still remain, and I'm not surprised that "let's do a substantial rewrite of much of our codebase from something that works perfectly fine to ... something else that works perfectly fine" is not hugely top priority for a fairly small project like this. Call that "people being roadblocks" if you will, but that doesn't strike me as fair. Neither of us get to decide where these people spend their time.
It's not as dire as you think :) Gimp should get Wayland support automatically when they complete the move to Gtk3 (which supports Wayland, Gtk2 does not) and the betas already support Wayland [1]. Enlightenment has clear plans for a Wayland mode [2]. Xfce has stated they'll support it too of course, but it's the largest change they'd be making in decades so it's understandable they're cautious. Maybe the momentum will have people get involved for Xfce, I'm pretty hopeful for all projects.
