Actually I do not care so much about  cargo-{development-}inputs fields.

The much more serious issue is that we are not able to build non-trivial
Rust applications: Given a package which needs to add phases, e.g. for
fixing Cargo.toml, we would need to run each package's phases when
building any depending package.
