[bindings] Allow unused fns that the bindings can call but don't

We no longer have any public `Option<Signatures>` in our code, and
thus get warnings that the two functions which support it are
unused. Instead of removing support for them (which we may need in
the future), we add `#[allow(unused)]`.
