  Will do this and fix review comments on weekend (or earlier if I can).

  Well, it has `active` property in KWayland that is true only if at least one client is connected (if I remember my code from 6 months back correctly), so I can expose it and use here. Will this suffice?

  No, sorry. This patchset was ready long before the GNOME news. I use different idea here that was proposed by Martin Graesslin, with GBM and Wayland protocol we actually can pass file descriptors to video buffer objects from one app to another 
  so KWin is passing BOs to KRfb which then can do all heavy-lifting without hurting KWin performance or stability.
