  # Can not delete this method with out a deprecation strategy.

  # pre 1.0.

  #
  # Actually, on the deprecation note. This method isn't really the problem.
  # The problem is the default generated pre-commit hook. It shouldn't have
  # logic in it. The we have freedom to change the gem implementation however
  # we want, and nobody is forced to update their pre-commit binary.
