I would like to make this test more sophisticated.

Namely, we should plug the unconstrained associated types of the object type with placeholders, and then detect cases where the placeholders don't end up being what the blanket impl would have predicted. In that case, we know that we can use a dyn Trait to abuse the unsoundness in #57893.

However, first I'd like to see what the most naïve fallout of this is.

Reject blanket object impls that are possibly incoherent wrt associated types

I would like to make this test more sophisticated.

Namely, we should plug the unconstrained associated types of the object type with placeholders, and then detect cases where the placeholders *don't* end up being what the blanket impl would have predicted. In that case, we know that we can use a `dyn Trait` to abuse the unsoundness in rust-lang#57893.

However, first I'd like to see what the most naïve fallout of this is.
