I don't know if there are other jest plugins worth considering. I think ideally there'd be a wildcard rule like jest-* that lined up right after jest, but I didn't want to get too deep in.

Minimally, this will satisfy my own project's needs.

That’s exactly the contributions I get excited about! Let’s not worry about theoretical gains. Scratch your own itch and someone else can come in after with more.
