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.
