*This* virtio-fb doesn't, but one feature I think a lot of users
(including me) would like is:

Option to resize the guest desktop when the host desktop / host
window / VNC client resizes.

Tell the guest to provide multiple desktops when the host has
multiple desktops, so things like twin monitors work nicely with
guests.

Relay EDID/Xrandr information and updates from host to guest, and
generally handle hotplugging host monitors nicely.

Are there any real hardware standards worth emulating which do that?
