Not really. People in the Rust community have shown a great deal of willingness to standardize on a handful of traits, so things tend to be intercompatible. That might change, I guess. In any case, there's no point in using an async I/O model for the majority of use cases many of the people using Rust are interested in, so people standardizing on something else for those usecases isn't a problem.
