Well, a client that knows it's not going to use a stream as a basis
for prioritization can discard the state immediately.  A server
doesn't have that opportunity, so it has to use some heuristics to
determine what to keep and what to delete.

The point is that prioritization state isn't strictly tied to stream
state.  If stream 7 depends - or could depend - on stream 5, stream 5
might be closed at the server when initial or updated priority
information for stream 7 arrives.  If the server cares about
respecting prioritization for stream 7, it had best find a way to keep
stream 5 in its priority graph somehow.
