Right, it's completely fine. You'd have to be an oracle to write software that never rots at all. I'm not criticising anyone who has written or signed off on adding code to any standard library that was later deprecated. However, in hindsight it was the right call to not add some libraries to Rust's standard library. In some cases, they turned out to be dead ends (rustc_serialize) or needed a lot more time to bake (rand).
