See discussion in encode/httpx#1283.
Completely ignoring a lint should be done with careful thought and agreement. I for one would rather ignore it where it's necessary, rather than across the entire project, but others in @encode/maintainers need to chime in as well.

Only 4 lines are affected so I could do that too.

I'm merging this to unblock other PRs, we can reassess later whether we're okay keeping inline # noqa, or if we'd like to just ignore this error in setup.cfg, or just pin to the previous version. 👍

Just to mention that I really do think it's worth ignoring this in setup.cfg. I wouldn't have an issue with this if it only failed linting on except BaseException, but except Exception is a perfectly normal sensible thing to do, and shouldn't need per-line linter exclusions. 😃

We could also review all our except Exception cases in tandem with that change, in order to assess if any of them could be more tightly defined.
