-Subject: [PATCH 1/3] minimize the rust-std component
-
-This splits out a rustc-dev component with the compiler crates, and
-keeps the status quo of default installed files on nightly. The default
-changing to not install compiler libraries by default is left for a
-future pull request.
-
-However, on stable and beta, this does remove the compiler libraries
-from the set of libraries installed by default, as they are never needed
-there (per our stability story, they "cannot" be used).
