I don't think that's universally true. repr(transparent) guarantees the layout
and ABI match the inner field. The wrapper is passed through calls exactly as
the field would be. repr(C) guarantees C-compatible layout and makes the type
follow the platform's C ABI for passing an aggregate, which isn't always how the
bare field is passed.
