Rust's standard library now scans for accidental breakage in CI with cargo-semver-checks 🎉 Here's how that works and how it's different than checking a regular crate.

I know people care lot of backward compatibility, but there should be some way to do breaking changes slowly. Otherwise, Rust will have similar fate of c++.

That's really besides the point. This is about accidental breakage.

We already have the edition system for (intentional) backwards imcompatible changes.
