 It's OK to complain about not having it yet in the log file, but I think
 we should still be able to build circuits. This is the purpose why one
 would raise `NumEntryGuards` from 1 to some higher value, to gain better
 connectivity against greater probability of running into a hostile guard.

 Hey I think this comment was meant to go on #21969?
