I make liberal use of them, it's become one of my biggest selling point of
RESTCONF over rolling your own REST API for management.

I avoided implementing SSEs over HTTP/1.1  *because* I used a lot of
notifications and separate session for each subscription obviously doesn't
scale.  I went w/websockets for now with the idea I'd reimplement when a
reasonable draft is assembled.  I had hopes for SSE over HTTP/2 because
seems rather straightforward and in theory should scale.  Obviously with
websockets, my implementation doesn't interop w/other RESTCONF/NETCONF
systems/libs but hoping to change that with this draft.

I don't understand the details surrounding using an RPC to make a dynamic
subscription.  Unless it's optional, then I can start to understand.
