I'm kind of getting convinced that it may not be worth trying to
manage that in the proxy, especially when we don't know of any modem
behaving correctly w.r.t. indications being sent when not supposed to
(or do we know of any).

Greg, will leave this up to you, as I guess you'll test it and have
more insights on how it's going to work within the proxy. If you think
that it is not worth sending to all clients notifications that arrived
when no client had them configured, let's just filter them out in the
proxy itself.
