I guess there could be a lint that detects a given item being `use`d
which we could use in some cases like this.

I took a quick look, and I see `enum_glob_use`, but that seems global
without a way to filter, and it doesn't cover direct `use`s.

Then there is `wildcard_imports`, and that seems fairly usable (it has
an allowed list), but of course doesn't cover non-wildcard ones.

Cheers,
