- Always name the non-FFI-safe - Explain *why* the type is not FFI-safe - Stop vaguely gesturing at structs/enums/unions if the non-FFI-safe types occured in a field. The last part is arguably a regression, but it's minor now that the non-FFI-safe type is actually named. Removing it avoids some code duplication.
