This is currently impossible because it causes impl conflicts with any generic #[derive(KnownLayout)]. However, if we could get Rust to understand that we're only emitting a derive for unsized types, it'd be possible. Prototyped in 5601ac4, but Rust doesn't know that TrailingField: KnownLayout<PointerMetadata = usize> implies TrailingField: !Sized. Maybe we can spell TrailingField: !Sized somehow?
