It only takes 3.3 seconds when the Rust code was unchanged. However, it would be nice if even that could be saved.

I assume/hope this would also allow pre-building the native libraries in some other way (in my case, in parallel for all 4 architectures in separate CI runners), and copying them to the right place, resulting in gradle skipping the Rust build entirely.
