I like the direction where this is going.

You have a test case for adding a throttling filter. Can we also remove
it again or is there still a problem with that? I seem to remember that
that was a bit trickier, though I'm not sure what it was. Was it that we
can't have the throttle node without a file, so it would possibly still
have permission conflicts?
