Ref: https://github.com/astral-sh/ruff/pull/21779/files/d314aa859dcf9a6ffb006a594d7ca0431dd4fab2#r2586995420

Specifically, the auto-import AST scanner will assume that all conditionals are true. This could lead to some symbols not being declared as exported when they ought to be.

Instead, we might consider preferring false positives to false negatives by unioning __all__ definitions in such cases. We might suggest some things incorrectly, but thisis probably better than not suggesting correct symbols.
