In case you haven't seen, User:Rillke on Commons has implemented a

notifications of different types, e.g. policy changes, new features,

Here's a screenshot of the "subscription" interface:

IMO that type of gadget lends supports to the notion of shooting for a
subscription model to be ultimately integrated with Echo so that users
can get standard read-once notifications about things they care about
while keeping the core UI clutter-free.
My understanding was that this sort of "feed" stuff was intended for a different subsystem that would become a part of Flow.
