This seems maybe-perilous because a symlink might point outside the working copy, or might point at an external/submodule which hasn't been initialized. I'd worry false positives like this might overwhelm true positives. That said, this .arclint makes it fairly easy to deal with this kind of stuff with exclusion/inclusion rules.

Possibly, one real issue at the moment however, is that arc lint will fail to lint these files altogether (none of the linters will be able to read the contents of such a file).
