------------------------------+------------------------------
 As we add more padding machines across different Tor versions, padding
 negotiation will become more and more likely to fail. We could send a
 preference list to the relay instead, so that if any of the machines we
 could use are supported, they would be chosen in preference order.

 We could also add a delay field asking the relay to delay before
 responding, as an alternate way to deal with concerns in #30172.
