Nobody really constrains protocols from carrying a local IP address
around any more than anyone constrains from putting local addresses
into a text message. It's just that communicating by naively replying
to such an embedded address is unlikely to work.
Actually, NAT *does* constrain protocols from carrying around a local
IP address if it's emitted out into the world. Remember that if it's
a LOCAL address, it's used *only* behind the NAT, and nobody cares about
that case.
The problem with NAT is the same problem as people who put locally usable
addresses in their .signature files - the NAT *doesnt* fix those up when
it becomes a non-local address BY VIRTUE OF PASSING THROUGH THE NAT.
