I'd like to assert that a third camp exists -- those who feel that  
From: and To: have gotten so confabulated that it is best to populate  
them with random haiku.

I believe this relates back to the usage of From and To tags and  
transaction matching rules. Once we moved transport-state into these  
application-layer features, we greatly reduced their utility from an  
application perspective. Something on my wish list for sip 3.0 . . .
