I don't think this will be an issue at all. The DRM driver should only
expose what's supported on the particular device that it drives. And
similarily userspace drivers should enumerate properties to find out
which ones are available. Atomic modeset is only the mechanism to make
sure it's all applied in one go. But that mechanism is completely
generic and can be applied to any properties, therefore no specific
knowledge about the available properties will be required in atomic
modesetting itself.
