I am working on patch series that implements this enhancement. My
current plan is to send the RFC changes along with the prototyping
code for review. I am currently making a small change to the original
monitor message to indicate whether it will accept the new Update
Notification format.  With the proposal of <monitor-cond-request>,  I
think it can be implied with the new message, and much cleaner.

The details of the new Update Notification is more involved that I
would like to prototype before proposing.
