I guess we could do that.
There seems to be different needs for different kinds of iterators, but
otherwise
I was thinking that an iterator could just skip invalid rects if found.
Then we
don't need a separate validation step, but OTOH user-space won't get
notified if
that was intended.
I'm not 100% sure user-space would do anything sensible with any error
information, though.

That could be done in core code in drm_atomic_plane_check().
