I suppose it would work ok as long as the code also doesn't try to set
auto-mode-alist locally in the buffer, both because that variable isn't
safe, and because I think it doesn't make sense to set it buffer-locally
anyhow.

I think this should work ok because hack-dir-local--get-variables checks
enable-remote-dir-locals.  In this case it will return nil, so the new
code in set-auto-mode will not do anything.
