• The AutoSplit redundant-casts are from _CField as a generic descriptor protocol typeshed#10595
• The new mypy hit (a true positive, fixed as part of this PR) is from Remove pathlib.PurePath.__eq__ typeshed#10662.
• The aiohttp and starlette hits are all from Make http.cookies.SimpleCookie non-generic typeshed#10701. It's quite a disruptive change, but I think it's the right thing to do.
• The mkosi hits are from Improve the accuracy of (default)dict.__(r)or__ typeshed#10679
