There was a problem hiding this comment.
The only case where this matters is not-well-formed projections, which who cares if they're treated as rigid or not.

…lcnr No need to `validate_alias_bound_self_from_param_env` in `assemble_alias_bound_candidates` We already fully normalize the self type before we reach `assemble_alias_bound_candidates`, so there's no reason to double check that a projection is truly rigid by checking param-env bounds. I think this is also blocked on us making sure to always normalize opaques: rust-lang#120549. r? lcnr
