def load_defaults(version)
  # Note that for 7.x, since all of the feature flag defaults have been
  # flipped to the new functionality, all of the settings for those
  # versions are to give old functionality. Because of this, it is
  # possible to recurse to later version to get all of the options to
  # turn off. Note that this won't be true when adding feature flags to
  # 9.x, since the default will be the old functionality until the next
  # major version is released. More likely, the recursion will have to go
  # in the other direction (towards earlier versions).
