Not a regression, this was always possible: https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=75705348c1fa16884e7912bc00bf9f92

The above code from the playground

trait Trait {
    type RefTarget;
}

impl Trait for () where Missing: Trait {}

struct Other {
    data: <() as Trait>::RefTarget,
}

const fn foo() {
    unsafe {
        std::mem::transmute::<Option<()>, Option<&Other>>(None);
    }
}

struct Foo {
    bar: [(); {
        foo();
        42
    }],
}

fn main() {}
