IMO, that's a bug in the configuration of those users because they're
overriding how cc-mode works, and the cc-mode manual describes in detail
the various ways to customise indentation.  So I don't see a need to
change the Emacs dir-locals-file to accommodate this use-case.

But that's just one opinion, and I'm not familiar with prevailing policy
on what to add to the Emacs dir-locals-file.
