Apparently not.

I've noticed the problem since march last year - the mutter-wayland folk
i chatted with at that time disclaimed any notion of "iconify", saying
hiding a window does not change the state and this is required for
live-previews when switching workspaces, etc. though they claimed full
support for ewmh NET_WM_STATE_HIDDEN

no, I couldn't figure out how to make raise-frame (select a different
frame and set input focus) work on mutter-wayland with gtkonly emacs.
gdk's calls do not work.

I think that's being punted, and relief is expected from some
"xdg-activation protocol"

The mutter model means invisible frames are still supposed to keep
rendering - they just wont be composited on the main workspace.

[I try use it once in a while - try to get it to do what I want,
encounter problems, give up for a month, etc.]
