This looks good, thank you for contributing to the project! I've made a comment on your changes and the CI is failing due to a linting error, but fix that up and this is good to merge.

Should I implement __reversed__ despite this fact or leave it unchanged?

Within reverse:

reversed_iter = reversed(string)

Right, but nowhere in your code do you construct a PyStringReverseIterator, so there's no way to actually get one in Python code.

Ok! I'll fix it in a moment.
