This is cool, though not having the standard library would be painful. Hopefully, there is some middle ground than jettisoning the entire std crate.

That's what libcore is; you still get a lot of the useful bits.

Most of the rest of libstd requires a known OS abstraction to exist.

Most of the algorithmy stuff (e.g. regex) has been moved out of the stdlib so you can pull it in separately if the crate supports no_std.

Not perfect, and a lot more crates could support no_std, but it's sometimes good enough.
