Wayland Protocols has long had a problem with new protocols sitting for months, to years at a time for even basic functionality.
This is hugely problematic when some protocols implement very primitive and basic functionality such as
frog-fifo-v1, which is needed for VSync to not cause GPU starvation under Wayland and also fix the dreaded application freezing when windows are occluded with FIFO/VSync enabled.
We need to get protocols into end-users hands quicker! The main reason many users are still using X11 is because of missing functionality that we can be shipping today, but is blocked for one reason or another.
Mesa MR to add support for the 'frog-fifo-v1' protocol :(https://github.com/misyltoad/frog-protocols)
I can't help but feel that they like Wayland the way it is, seeing as it's certainly not changed course
this is pretty much how it works in some cases, you need to port from one protocol to another, or to a different system altogether.
