Thanks for bringing that to my attention, I think it almost addresses
what I had in mind

s4.7 interoperability doesn't mention the fact that xmpp: and sip: have
slightly different sets of permitted characters for the user@ portion of
a URI.  s4.3 could probably be extended to define a subset that is
compatible with mailto:, xmpp: and sip: all at once
