I've understood it applies to "everything" in that you should not
commit large-scale NFC changes that don't have considerable benefit
(for some definition of considerable benefit). e.g., if you're fixing
a typo in an API and it hits a lot of files, that's fine because a
typo in an API is pretty egregious, but don't clang-format a bunch of
files and commit that because formatting isn't super critical and
instead we migrate it more slowly as the code gets touched.

Not everyone uses git; svn is still the official repository for the project.
