+1 to that, and also, to add:

It would, with kwin-zones and some nice Qt abstraction. But I don't
know if Qt would accept that for an experimental protocol, so I
haven't contributed it yet. Once done though, it would actually work
*better* than it does on X11 right now, it's a much smoother, less
annoying experience! The previous "simple" code was also extremely
complex under the hood.
All that said though, there is a fairly good chance that
xdg-session-management will do what you need, and that protocol has
broad support. Just be patient, and help out constructively if you
like and want things to go a bit faster.
