Wayland For Very Large Wall of Screens

[Linux Luser]

Xorg has been notorious for it's lack of multi-monitor support. Xinerama
was of course shimmed into place to help make one xscreen out of many.
Xinerama has had several drawbacks, however, one being performance, which
is usually compensated for in the industry by purchasing beefier graphics
cards.

Interestingly, XRandR claims to be the Xinerama replacement but doesn't
actually do what Xinerama does when multiple GPUs are involved. So right
now, it's a bit of mystery as to how to get a single, large desktop spanned
across many screens across many GPUs.

My question is, how does Wayland address multiple screens connected from
multiple graphics cards? Is this something that is completely and totally
handled by the compositor? If so, what compositors support a single dekstop
across multiple GPUs using Wayland?
