Yeah, it's not that we already have this information, it's a different approach to your current patch so that the functionality continues to live on `Type` (the benefit is that external consumers like downstreams or clang-tidy could continue to use the same interface they always have but get slightly more accurate results from it). If that is more effort than it's worth, I don't insist -- I'm not aware of any breakage from your current changes.
