Comment:

 The best fix for this is now probably under the heading of #18346
 (separating authority roles), but that doesn't mean this work would
 useless in the short-term.  Resilience fixes always look low-priority
 until something starts to explode.

 That said, we need to be careful about the proposed fix, to make sure that
 we only rate-limit the traffic we meant to rate-limit.
