Backwards compatibility to what? At the current time, there
is a fair amount of work in the WG to provide better guidelines
for both the SIPS URI as well as certificate use in SIP.

introducing this URI label? Even a host may have many DNS aliases,
but it will not be changed frequently. ]
A host may have many DNS aliases, yes. But if it is inserting
its URI in a R-R header, it can pick the alias whose canonical
name appears in the certificate.
Thanks.
