It shouldn't be ânoneâ, but I agree that the probability that a bridge's
client would extend to one of the bridge's entry guards is sufficiently
low that using `CREATE_FAST` for ''every'' circuit originating from a
bridge is acceptable.
But I also don't see a problem with a bridge's entry guards knowing that
it is a bridge, and I don't expect to be able to conceal that fact from
them when we change Tor to shove a bridge's clients' circuits through the
bridge's entry guards.
