After 9 years there is not even anything close to a universal standard and discussion across compositors has just started this year. That's embarrassing.
There's already been universal standards under discussion for a long time, for example xdg-shell for application windows. The recent discussions are attempting to make more standards, and has been going on for 2 or 3 years now. This is a lot of work, we're replacing the X11 stack which has a legacy going back over 20 years.
Which is implemented by literally who? I can see a GNOME mutter commit but can't find anyone else from a few minutes of googling.
Also: "As of June 2014, XDG-Shell protocol was not versioned and still prone to changes. "[1]
Who else loves to build software atop unstable APIs?

These should've been going on since the begin, really makes you think what kind of intent the Wayland founders had. Wayland is being pushed as the future and there still isn't even a way to have a universal fucking screenshotter, I guess it's a security feature to be locked out of your own desktop, right?
Uh... everyone. Mutter, Kwin, qwayland, wlroots, wlc, Sway, waymonad, Way Cooler, Weston, Enlightenment, and Mir all support it, as well as clients like GTK+, Qt, GLFW, SDL, EFL...
Look, you don't have to use Wayland. No one has said it's done, and Xorg still works fine. If it doesn't support everything you need, then it's not for you, no big deal.
Kinda have to agree here. Wayland is clearly the way forward for Linux desktop, but it's still at least 10 years behind WDDM, and Linux desktop people have maintained their love of needless fragmentation so I doubt it will ever catch up.
