I have a bit the feeling that users should use NOLINT* here instead of having a global option that is not seen in the code. Anonymous namespaces do not solve many of the remaining issues. A NOLINT in the code can grab the attention of a future developer and prompt a refactoring to avoid the pattern.

I don't have a strong opinion so if this is really wanted I won't object.
