 _could_ cause some change so we should measure, correct?

 It shouldn't make any change. The bwauths were early adopters of the value
 0 for this option, and in the many years since they started using 0, the
 rest of Tor caught up and everybody starting using zero. Then recently we
 took out the ability to choose anything other than 0.

 (In earlier Tor versions, the networkstatus_get_param("usecreatefast")
 defaulted to 1, and in more recent Tor versions, it defaults to 0. But in
 either case, it uses the param set by the consensus, which has been 0 for

 tl;dr I think this is not a big deal, just delete the line and move on.
