RxJS: Don’t Unsubscribe
Ben Lesh

Just what I needed to read!
Our components have `behavior` streams that gets reduced to each own `state` stream, then merges into a single app `state` stream.

The router could then just hand the next app `state` stream via a stream of streams, and thus automatically unsubscribe from all behaviors from the previous one.

Just thinking out loud here, and thanks for the inspiration, even if I might go overboard with it :-)
