It's idiomatic in rust not to chase some people's ideas about what idiomatic rust is, especially if that ideas include thinks like which libraries you use for what. If worked with rust (in a company) for over two years using rust for large code based is substainable. Sure at async fn's majorly changed for to do async IO, but that's basically it. Beside the async IO story other changes where often minor and fast to fix even without cargo fix. Also for a large code based there is zero reason to pedantically follow any new rust feature. It's actually idiomatic rust to not touch working/complete code just for some stile updates. And if you touch it anyway adding them cost you normally less than a minute. (Except async fn.)
