@jwillikers Would you be willing to provide the necessary second review for this PR?

[jwillikers]

Since wayland-protocols isn't a runtime dependency, most recipes incorporate it as a tool_requires. Here is where xkbcommon incorporates it. The downside to the tool_requires approach is that the same version of the protocols isn't properly propagated across dependencies, which seems like something that should be consistent across projects.

@valgur could you take a look at this?
Can we resolve this thread?
In that case, I'll try to merge this PR
