Rust has stability guarantees. As long as you don't update version of your binary/library new compiler versions can compile for that version and you can even interlink different editions so I really don't understand this argument. C++ modules had a proposal for something similar but it did not pass. It would also fix so many horrible backward compatible things haunts the language as a whole.
