Thanks for catching this concern. This project builds on jaraco/skeleton, which already has the bumps. I want to investigate when and why this project diverged to see if it was for some good reason.

Oh! It's the diffcov job, which doesn't exist upstream. Probably this project should either drop diffcov or maybe move it upstream, perhaps integrated into the test suite (instead of as a separate job). Otherwise, this job (and the same one in importlib_resources) will be a lingering maintenance concern.
