In theory we could compile SDL into the stubdomain and let it connect to the X server itself through TCP/IP. That however would be very far from efficient, as you loose memory-memory video blitting and go through network links. VNC server used to be possible in stubdomains, but the configuration is quite cumbersome: you have to assign the stubdomain an IP. Letting dom0 do this was much more simple, especially since dirtyness tracking is still done by the stubdomain, not dom0's ioemu.
