 In the event of DoS or braindead client behavior, directory authorities
 may need to rate limit or restrict connections. See #2665.

 Under these conditions, it would be useful if directory mirrors could also
 accept relay descriptor data, aggregate it, and hand it off to the
 authorities after eliminating duplicates. This coupled with #572 should
 allow the dirauths to better handle sudden traffic spikes by rate limiting
 or firewalling, without degrading the network.

 -prevoting-opinions.txt has a related idea, but we may want a push method
 rather than a pull?
