Editions solve an entirely separate problem, they were never meant to be LTS language snapshots. For example, C++ is considering adopting them in addition to their current versioning scheme: http://open-std.org/JTC1/SC22/WG21/docs/papers/2019/p1881r0.html http://open-std.org/JTC1/SC22/WG21/docs/papers/2019/p1881r0.... There has been discussion of a Rust LTS channel alongside stable/beta/nightly, which would try to solve that problem, but it has not been prioritized yet: https://github.com/rust-lang/rfcs/pull/2483 https://github.com/rust-lang/rfcs/pull/2483 An actual frozen language is also a possibility, but probably won't happen until more work happens on an independent specification. Which, in fact, people are also working on: https://ferrous-systems.com/blog/sealed-rust-the-pitch/ https://ferrous-systems.com/blog/sealed-rust-the-pitch/
