Hi,

Maybe this WG needs to figure out how to deliver core functionality and then
add to it over time.

For example, none of the notification drafts are critical or even important
for
getting YANG Push out the door.  We just needed (for core functionality)
to start notification delivery on a session, and RFC 5277 already does that.
All the new features are refinements and add-ons.

YANG Push could have been designed so it does not depend so heavily
on the subscription drafts. Now other non-standard solutions are getting
deployed instead of YANG Push.  There is no real business case to
replace all the proprietary work, especially if YANG Push drags on into
2019.
