Comment(by karsten):

 Oh well...  I'm afraid there's no quick-and-dirty way for me to find out
 if effects would be disastrous.  I tried feeding my old #2911 scripts with
 recent consensuses, but I'd have to rewrite large parts of it to consider
 advertised and measured bandwidth at the same time and to include the Fast
 flag in results.  That code runs quite slowly because it's really a lot of
 data, and that makes debugging harder.  Nothing of this is impossible, but
 I really need to focus on sponsor F today, tomorrow, and in the next two
 weeks, or we'll run into trouble there.  I can't really promise when I can
 look into this ticket.  Sorry.

 Of course, you could try what happens if you run the new code on one of
 the authorities and see if https://metrics.torproject.org/consensus-
 health.html#overlap shows something unusual.  As you can see, there's
 always some disagreement between authorities.  If a disaster happens, you
 should notice by the authority running the new code assigning very
 different Stable and Fast flags than the rest.
