Comment (by karsten):

 Let's not change Onionoo for this.  Two reasons that come to mind:
  - Whenever the directory authorities fall back to a consensus method
 lower than 24, the consensus would again contain relays without the Valid
 flag.  We'd have to include something in the header to indicate which
 flags we're removing.
  - This only affects relays, not bridges.  We'd have to indicate in the
 header that the set of removed flags only applies to relays.
 So, I don't think this is worth the effort.  Compression should take care
 of this somewhat redundant information.  Or, if we'd be worried about
 these eight or so characters per relay (`,"Valid"`) , we should reconsider
 encoding flags more efficiently than writing them out in full.

 Regarding removing these flags from Atlas, I'm not sure if the second
 reason above wouldn't apply there as well: bridges can still be listed
 without the Valid flag in the status, so it might be wrong to just drop
 that flag from all displayed bridges.  Not sure how relevant that is,
 though.
