I would remove the mention of different field names. The main purpose of
the Registry AISI is to discourage unnecessary proliferation of lots of
headers all doing the same thing. So whichever the registry endorses, that
effectively causes the others to be deprecated.
As to the problems in determining the address to which it refers (I
presume that particular issue does not arise in its HTTP usage), either it
is too severe a problem, in which case the proper procedure is for someone
to write a standards-track proposal, possibly introducing some additional
syntax; or else it is OK as it stands, in which case it should be
registered. If someone does produce such a draft, then of course it could be
registered in the provisional registry.
