I'm not sure it's good to always ignore the rule on overrides.
I have some classes that look like this:

class A:
    def foo(**kwargs):
        pass

class B(A):
    @override
    def foo(*, filter, **kwargs):
        pass

Previously, it was triggering A002 because filter is a builtin which I had to silence (couldn't rename because of backward compatibility).
I think that was fair.
But now the rule is not triggered anymore.
