I think there is a chance to get it part of the standard, but given tha=

"mainstream window managers" are working on Wayland currently I wouldn'=

expect that they will implement support for it. On Wayland it is just a=

You need to prepare a change to the spec. The tricky part here is to ke=
ep=20
backwards compatibility. We must expect that some applications do "smar=

things like stopping video playback if they are not on the current desk=

(That's the main reason why KWin didn't go the road i3 went: we cannot =

existing applications).
