Agreed (and with your first two points as well).

I agree with you and Paul on this.  The key place where I think
Paul and I disagree is that I don't see creation of a registry
into which candidate label separator characters could be
inserted for information (along with whatever explanations are
available as to why that is or is not appropriate) as either a
big deal or requiring any sort of normative / standards action
classification. Neither of us believe it should be part of the
effort of this WG (or, I think, any successor WG).

FWIW, I think ICANN knows far less about UIs and similar issues
than the IETF and has a tendency to turn any project like this
into a big deal.  By contrast, the IETF has created several
registries that are managed more or less for the convenience of
the broader community, without much (or any) normative effect
other than public notice that someone is already using a
particular identifier and promoting the exchange of information.

If we are not going to create a registry, I'm opposed to
fine-tuning "mapping" with additional, last-minute, characters
and would argue that the character list should be removed from
the dot-oid mapping discussion because the list is not complete
and cannot be perfected in a reasonable amount of time.
