You can achieve this by declaring `K` and `V` manually with the variance you want. auto variance should be safe by default, if you want to do unsafe things, then you have to be explicit, I don’t think that is too much to ask. PEP695 was supposed to be a simplification for the most common cases, it was never intended to replace manually specifying `TypeVar` variance entirely, since that is not possible.
