Comment (by karsten):

 Hmm.  The use cases you describe make sense for adding such marker
 interfaces sound plausible.  But it also seems easy to introduce these
 interfaces and potentially difficult to deprecate and remove them if we
 don't want them anymore.  Should we wait with adding them until we need
 them?
