An RFC can only be obsoleted by a new RFC. The draft mentioned is the draft
that was published as RFC 2976. There has not been any updates to INFO.

The INFO message for an existing dialog, like a BYE message, would contain
Route headers and a Request-URI equal to the remote target (i.e. the Contact
from the request/response that established the dialog) which would prevent a
proxy from forking it.
