@frog @emersion But anyone can just make extensions and ship them outside of wayland-protocols. This was even a goal in the early days when @krh was still developing Wayland. Let downstreams mature extensions, and then let them grow their support organically.
I think that idea still carries, but we need to think how to deal with the fragmentation.
wayland-protocols partly came about from the desire to have "blessed ground" for known-good extensions.
