Just a note, it would be good to include from __future__ import annotations when adding the annotations. With jaraco.test there was an issue with older pytest version not exporting the annotation properly even though internally it works ok.

I thought that was the main goal of these PRs. Is it only checking mypy annotations of third-party dependencies?

[Avasam]

It's only re-enabling basic mypy type-checking as per jaraco/skeleton#143 . And doing the fixes necessary. Sometimes that includes fixing some annotations or suppression comments, sometimes like this PR, we only need to indicate that we know a dependency is untyped.

Some skeleton-based projects were ready to be strictly checked and/or marked as py.typed, so I marked those as such as I went along (some were only missing a few easy annotations, so I completed those when I felt like it).

Projects that affect setuptools (https://github.com/pypa/setuptools/blob/3106af0512fe67464a8b5e7524c07fddf7717660/mypy.ini#L44-L50) I may put more effort into actually completing annotations.
