 Oh, oops!

 > otherwise it seems fine to me.  I'm guessing that we should merge this
 when we make the change that does the "weight=10" removal in
 fallback_dirs.inc, and not before?

 We can merge this earlier or at same time as we merge the weight removal
 branch in #22271 to master.
 And we can backport this earlier or at the same time as we backport the
 newly generated list with no weights in #24801.

 But the timing is really not that important, if we do it out of sync and
 try authorities at 1x or 0.01x the fallback rate, no-one is likely to
 If I had to pick one, I'd go for lower load on the authorities, which is
 "merge this ticket before the other tickets".
 (Clients already try authorities after 3 fallback failures, so having them
 in the fallback list is probably redundant. Except in configs where we
 remove all the default fallbacks!)
