I gather from this that X11 will be completely unaffected? Wanting to
depend on unreleased software is unprecedented for a component of
kde-workspace providing a commonly expected feature - and is something
I find objectionable. Especially if the dependency offers no benefits
to those of us whom recieve no benefit from the increase in

Can you please clarify what you mean by we *have* to depend on it?
Does this mean which of the following:
* CMake level check making KWin completely unavailable to people
without Mesa 7.11
* Runtime level check making all compositing unavailable to people
without Mesa 7.11 - regardless of whether it is X or Wayland
* Runtime level check only concerning Wayland
Either of options 1 and 2 are completely unacceptable under any
circumstances - considering that people who will be developing for 4.8
will be doing so under distributions which ship 4.7 - which will
probably only have Mesa 7.10.
Compositing alters the way the window system operates and can expose
bugs - and by imposing these dependencies you are inhibiting the
ability of other developers to triage and fix bugs or other defects.
