…uard Replace the HIR-level BoundPolarity::Maybe check with a tcx-level is_sized() query (Ty::new_param + is_sized(cx.tcx, cx.typing_env())). This correctly handles: - T: ?Sized + Sized / T: Clone → is_sized returns true → lint fires - T: MetaSized / T: PointeeSized (sized_hierarchy) → is_sized false → suppressed - for<'x> T: 'r (higher-ranked) → predicate.bound_generic_params.is_empty() guard lets lint fire; RFC 599 excludes higher-ranked predicates from object lifetime defaulting Also remove the lint description disclaimer added in rust-lang#157998 since the lint now correctly handles the object lifetime default case for unsized type params.
