One small tidbit I noticed this morning that slipped my mind - I had put
#[repr(transparent)] here because when I was initially figuring out the
bindings before patch submission I had `Registration` embed faux_device, which
ended up not really making any sense and getting replaced with the NonNull. So
we should be able to drop the #[repr(transparent)] here
