You need to engage the Wayland and compositor community and explain why you 
need the features you think you do. Some of them may be possible already, some 
may be in the pipeline, some others may not be because no one thought there 
was a valid use-case.

Just be careful to explain the use-case, not the means by which you are used 
to accomplishing it in X11. For example, Wayland does not support grabbing the 
keyboard or mouse, but that is not needed for closing popups if the proper 
protocol for handling popups exists, and it does.

You can, by shipping only the Qt xcb protocol with your application (if you 
ship a binary) or by programmatically forcing it to be the platform if you 
distribute sources. There's no discussion about sunsetting the Xwayland 
support, so for the next 5+ years, this is a valid approach.

That works too, but of course it will cover the desktop's fixtures, which may 
not be desired.

Again, you need to explain the use-cases, not just "move windows around and 
stack them in a particular order".
