This was the whole point of https://github.com/rust-lang/rust/pull/77802. - Pass `pkg.name()` to `parse()`. This can't pass the `Package` directly because `PackageInner` is an `Rc` and therefore not thread-safe. Note that `pkg_name` was previously a *description* of the package, not the name passed with `--crate-name`.
