Not sure what you mean exactly. The use case we had in mind when we
wrote that sentence was a LW4o6 B4 that would fetch as many ports as it
could to use as a port pool. So it doesn't know in advance how many
ports it will use. It's just asking for as many as the AFTR is willing
to provide. I suppose a heuristic to release unused ports could be
possible, but it would make much more sense to simply configure the
maximum port set size on the AFTR to a value that makes operational sense.

Does that answer your question? Do you think changes to the text are
warranted?
