We don't want to keep the tool settings in the sources, but what's wrong
with keeping them next to the sources? We have
src/tools/editor/emacs.samples already. This just moves some of the
contents to .dir-locals.el, where it would be more useful.

No one is required to use this, and seasoned hackers aren't exactly the
target audience anyway.

I think you are confusing two separate changes. The proposed addition
of .dir-locals.el is entirely optional. (Well, I have removed the Perl
settings from emacs.samples. We can keep them if disabling local
variables is a wide-spread practice.) The C mode settings in the new
emacs.samples file are just as functional as the old ones, except they
are arguably better.
