Sorry to be tardy in responding...

As I stated almost 2 years ago when this draft was introduced:

a)The problem the draft is addressing is real and the solution useful

b)There are implementations which have already addressed this problem with no interoperability issues

c)I do not see that any changes have been made to the BFD protocol (e.g. RFC 5881)

Therefore, I think this should go forward - but as Informational.
