The intent is to do the draft-ietf-bfd republish next week and include text
to address these.

We believe that this is currently out of scope for the work.  However, as I
have discussed with Albert, it's not unusual for BFD features to be used in
unexpected ways.  If there continues to be interest in discussing this, it
might be worth adding an appendix covering this use case.
