Thanks for the backstory. It's always much preferable to have as few dependencies for bootstrapping a platform as possible. Therefore, this is a good development. Similarly, I'm hopeful the Python requirement in the new Rust based build system for rust itself will be removed sooner than later. Building Rust already requires Rust, so what's more logical than replacing the Python part with Rust. It will definitely be easier to get going than having to install some Python modules first. Same improvement should happen in servo's build system which since a few months or a little longer depends on virtualenv.
