Instead of a large std tied to the stability guarantees of the labguage, I would like to see something akin yo "stdlib distributions", where a versioned set of community libraries can be depended on to interoperate without duplicated deps in your tree. This decoupling would allow Rust to remain 1.X while the equivalent of the stdlib can bump their major version every, lets say, 3 years, without breaking older projects. You'll notice that this is almost the same thing we have today, and anyone could start it just by creating a crate called "my-std" with the list of dependencies they want to provide.
