Very surprised to hear that, since editions are exactly the kind of mechanism Rust is using to make sure software will keep working unchanged for decades.

The Rust compiler can build a 2024 edition application which depends on a 2015 edition library, which in turn depends on a 2018 edition library.

Every crate can upgrade at their own pace, or even never at all.

Oh, I'm aware about the benefits of editions. For some reason, I've misread OP's comment.
