I also think it sounds good. And I think that there is some leeway on
the interpretation of the constraints object; the UA could stop+fail as
soon as constraints are declared if this is not supported, or it could
dig into the constraints one level. If no mandatory constraints are
declared the UA could deliver the stream even if the actual
non-mandatory constraints are not checked (as these are similar to hints).
