Comment (by pastly):

 This is interesting to me. I'm going to see if I have time to test
 hdevalence's branch and write tests.

 This way, we can preserve the currently expected behaviour without
 surprising users. We can revert my patch in #18113 and just flip the
 config variable on for TB users, and, likewise, non-TB users who really
 want this can opt-in to enabling it.

 How much do we care about people who use non-default torrcs for the TBB?
 The only concern I want to raise is that if enough people remove the
 ShuffleBridges option and #18113 is reverted, then there could be unfair
 load on the first few bridges again.
