That grep pattern makes zero sense.

Why would */ be special at all? It isn't.

  $ git grep SPDX-License-Identifier: | wc -l
  52418

and a *LOT* of those are shell scripts and use "#", or are C sources
and use "//" etc.

So your "standardization" is completely pointless. Anybody who expects
that pattern just doing something fundamentally wrong, because the
pattern you want to standardize around is simply not valid.
