Everybody is pushing it and trying to convince the people who have problems with it that it's completely fine and their problems aren't important (like blind people being completely unable to use the computer).
At some point the pipewire of display will come along and we'll all forget wayland was ever a proposed solution.
Pulseaudio is both a protocol and also an implementation of that protocol. Pipewire also implements the pulseaudio protocol, hence its compatibility with all existing software.
Wayland is a protocol only. Every compositor - and there are many - implements it "from scratch". The "pipewire of display" would simply be yet another Wayland compositor. No one is going to solve the problems of Wayland in one fell swoop by releasing another Wayland compositor. What is actually happening is that problems are being gradually solved by the introduction of protocol extensions, which usually get adopted by other compositors after achieving success in one.
On a separate note, I think it's probably true that Wayland has significant drawbacks that preclude it from being an obvious replacement.
