I was not asking for that. I was answering your question. You asked for evidence of rust releases being abandonware. I gave it to you. Someone else trying to ameliorate Rust releases does not change this reality.
Use language features not considered “stable rust” that are later discarded and you will learn it is abandonware very quickly. In any case, you asked for proof and now have it. You should be saying thank you instead of trying to argue.
I mean, thank you, but calling Rust abandonware just because it uses a rolling release model is misleading IMO. Also there's nothing wrong with unstable features being discarded, they're unstable.
