I think that Unicode calls these "confusables", but some of my
discussion with UTC members makes me think that they regard them all
as more or less the same thing.

Well, we do already have running code for this, because we don't seem
to think that app1e.com requires anything except the ability of the
trademark holder to take enforcement action.  I don't get why these
additional cases are supposed to be different.

And that, of course, is where they will stop.  ICANN is capable of
making rules about the root zone, but it cannot set policies for the
zones below -- that's up to the operators of those zones.
