Wasn't SHIM supposed to be used to attach "internet headers" (from
e-mail, HTTP document, etc.) as-they-are? IMHO adding special cases,
which have to be translated breaks the protocol. What if we find another
collision in future? Does any SHIM implementation, whatever it is used
for, need to know all the special cases?

IMHO it would be much better to create SHIM profiles and declare the
profile with the header set. When profile is "rfc822", then RFC 822
rules apply, etc. Multiple SHIM elements with different profiles could
be added to one stanza then. And we could use just "to", "from", etc.
header names for XMPP-headers then too, but I guess it is to late for
this change.
