demonstrate that the extensions to Cargo are expressive enough
Only rustbuild would know about bootstrapping stages, but each stage should be buildable as a single Cargo workspace / invocation of Cargo. In particular it should be possible to build Core through std through end executables like rustc and rustfmt in a single workspace/stage.
