I am really new to the debate and do not know the backgrounds,
but how is wayland + mutter supposed to deliver united graphical
experience if every non-gtk application is supposed to draw it's
own decorations?

We should not make decisions about our window decorations look.
Can we just ask Qt, use CSD default for the given system if running
under wayland?
