 * resolution:   => implemented


Comment:

 I've looked at the code and run a test, and it seems that with
 FetchUselessDescriptors, the client stores parsed versions of both
 consensus objects, so a new fallback won't be needed there.  The comment
 about handling "a consensus we don't parse, but which we do cache" is
 talking about an expected future feature that we haven't implemented yet,
 where we teach caches to download flavors that they weren't originally
 programmed to know about.

 Per above and per your review, I'll merge this as-is.  Thanks for looking
 at it, and for verifying that it won't mess up #20667!
