Optional dependencies not respected in bzlmod

Hello,
I have a non cargo setup via bzlmod. When i set `default_features= False` in crate.spec, the rust_library target generated in the crate's BUILD file still has dependencies that should only be set when that specific feature is present.

This can sometimes massively increase build time when the crate has a lot of optional feature-based dependencies.
If it helps, I can create a reproduction repo?
