As a maintainer for Redux, Redux Toolkit, and React-Redux, I can tell you that we would _love_ to have several additional features in TS that would make our library TS types much easier to maintain. Like, say, partially specified generics. Tanner Linsley (author of React Table, React Query, and other similar libs) has expressed similar concerns. (I'm actually starting to work on a talk for the upcoming TS Congress conference about "lessons learned maintaining TS libs", and this will be one of the things I point to.)
