I empirically believe that it's a few years too early to freeze the minimum 
required Rust version. Who knows what *other* relevant feature Rust itself or 
the Rust C bindings will develop in the next few years.

If the support is merged in the development branch, just use it. You can 
always adjust later if needed.
