This is mindeps. Possibly we should bump it up, but dependabot is just wrong about this.

I'd like to add a CI job which checks that mindeps don't exceed our declared lower bounds, as part of what we do with metadata examination. That will at least make this sort of junk unsafe to merge.

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
