I don't think this suggestion justifies technical debt that it introduces, and I would personally close #89590 as wontfix.
The "expected trait, found struct Struct" message clearly identifies what is expected in the position before for.

If we could either move the logic out of the way so that the code is easier to read, or simplify and only signal that we're resolving an impl item header and emit not a structured suggestion but a note, it would be better.

@petrochenkov are you concerned with the growth of DiagnosticMetadata, the added logic, or both?
