I tried this code:

pub trait Trait {
    fn f();
}
impl<T> Trait for T {
    fn f() {}
}

pub mod inner {
    use crate::Trait;
    /// Link to [S::f]
    pub struct S;
}

I expected to see this happen: The link resolves to <S as Trait>::f

Instead, this happened: rustdoc can't resolve the link:

warning: unresolved link to `S::f`
  --> blanket.rs:10:18
   |
10 |     /// Link to [S::f]
   |                  ^^^^ the struct `S` has no field or associated item named `f`
   |
   = note: `#[warn(broken_intra_doc_links)]` on by default

After seeing #78761 I'm strongly considering getting rid of blanket impls altogether, clearly no one has been using them or they would have opened an issue. @Manishearth what do you think?
