I must say this is not very convincing.

What bothers me is that .dir-locals.el in a directory is not meant for
compilation-mode and similar modes, so settings there that are not
specific to modes could get in the way in *compilation* and "grep*
buffers.  But if this is optional behavior, by default off, I don't
think I'd mind.
