I assume you wanted to comment on the sixth patch.
Yes, it's useful, because that way we avoid using a deprecated
binding, that we would have to mix the newer binding which would be
completely inconsistent, and that way we use the generic binding that
everyone uses everywhere.
The backward compatibility is just here to avoid breaking the ABI.
