No, "completely useless" is just plain wrong.

The optional disambiguating doubledash is the standard way to erm, well,
to disambiguate whatever there is to disambiguate.  Not only refs and
filenames, but also e.g. options and filenames:

  $ git checkout --option-looking-file
  error: unknown option `option-looking-file'
  usage: git checkout [<options>] <branch>
  <...>
  $ git checkout -- --option-looking-file
  error: pathspec '--option-looking-file' did not match any file(s) known to git.

Note that this is not at all specific to Git, many other programs
support the optional disambiguating doubledash as well:

  $ touch --option-looking-file
  touch: unrecognized option '--option-looking-file'
  Try 'touch --help' for more information.
  $ touch -- --option-looking-file
  $ ls --option-looking-file
  ls: unrecognized option '--option-looking-file'
  Try 'ls --help' for more information.
  $ ls -- --option-looking-file
  --option-looking-file

Please do not make it mandatory.
