How about:

Sending or receiving a PRIORITY frame does not affect the state of any
stream (Section 5.1), only the priority of the identified stream is
altered.

I think that the "first use of a new stream identifier" text is still
problematic, but I don't know how to deal with that without performing
more surgery.
