I have no idea.

Perhaps open a merge request adding it to
https://gitlab.freedesktop.org/xdg/xdg-specs/-/blob/master/wm-spec/wm-spec.xml,
but you should probably familiarize with what happened the last time it
was attempted, which was in 2011:

https://mail.gnome.org/archives/wm-spec-list/2011-October/msg00006.html

But you can just as well go and implement it anyway, if you need this
kind of frame synchronization on X11; it's unrealistic that adding it to
wm-spec.xml would mean any changes were to be made to it anyway.
