From the minutes, the WG agrees that this is a problem worth solving, but the current documented isn't quite right.  Please update the draft to:

1) focus on introducing a way to configure subscriptions such that any "notif" draft can be used to send notifications out line cards.
1a) do not focus on any particular "notif" transport (at least not in this draft)
1b) assume that the notif transports may be either UDP or TCP (more likely TCP)
1c) assume that the notif transports may be encrypted or not encrypted

2) per Ignas's comment, explicitly state how transport congestion and related aspects are or are not being taken into account.
2a) my opinion is that this draft sets up up the *potential* for a problem (and should say so), but it is likely that the particular "notif" transport used will matter greatly (e.g., unencrypted UDP is less heavy than encrypted TCP).
2b) also my opinion, this draft is comparable to the subscribed-notifications draft in this regard, so lifting text from there should be possible.  Since there is an overlap of authors on both drafts, hopefully what's needed is well understood.

An adoption call will proceed once the update is published addressing the above.
