I think we could shoe-horn this use-case into the current framework by
using a special crtc-property "ignore attached fb, use this default
color instead". But I think this would be better done in a second step
when we tackle atomic vsync flips across multiple planes and the
underlying crtc - that might also require us to change certain
properties in the same flip command.
