You missed an email explaining that: if we mandate not changing "safe" call-id values, all b2bua's along the path have to stop changing it, and the UAC has to create a "safe" one.  If we do a new header, only some b2bua's need to change for matching to work in most cases.  All of them would need to pass the header for it to work, but my assumption is that's more likely.  It may be a false assumption, but from the traces I get to see, it looks like new headers get through fairly often. (at least those without URI's)
