Oh, okay, so this works as expected. But since googling "change
indentation
size" always gives using specifically c-basic-offset (e.g.

I guess it's safe to assume most of Emacs users has it changed. So
it's useful
to add this to dir-locals anyway.
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.
