Make sure no one adds back a -b option:

  hg strip [-k] [-f] [-B bookmark] [-r] REV...
  
  strip changesets and all their descendants from the repository
  
  (use "hg help -e strip" to show help for the strip extension)
  
  options ([+] can be repeated):
  
   -r --rev REV [+]        strip specified revision (optional, can specify
                           revisions without this option)
   -f --force              force removal of changesets, discard uncommitted
                           changes (no backup)
      --no-backup          no backups
   -k --keep               do not modify working directory during strip
   -B --bookmark VALUE [+] remove revs only reachable from given bookmark
      --mq                 operate on patch repository
