I don't know if it helps, but I just ran in to this when I followed the advice at (1) because I wanted to type hint a method with the type of the enclosing class. This broke a package I'm working on in parallel (2) because it uses dataclasses.fields internally. I'm not sure what the advice would be here, should my package detect if the caller has `from __future__ import annotations` and do something?
