Is there a good way to
#[allow] a lint for a generated impl, that also works in the presence of an outer
The built-in derives seem to have such a mechanism, for example they won't fire the
deprecated lint even though the generated impl would otherwise trigger it.
Or is the

Huh, they also attach
#[allow(unused_qualifications)] to the impl, but that does break when
#[forbid(unused_qualifications)] is present
