We have the entire family of mid-call "telephony tunneling" events for
which we've previously agreed to use INFO as use cases.

I think the clear factor between scoping events to an INVITE dialog
(INFO) versus a SUBSCRIBE dialog is whether the events being reported
are completely bounded by an INVITE dialog. That is, they're what we
would have previously called "mid-call events".  If they have no
meaningful context before the INVITE or after the BYE, then they may be
reasonably considered to be INFO events.
