The portability is needed to let many runtimes grow without pains of fragmentation. Currently tokio dominates, and you either use tokio, or you lose access to a large portion of the ecosystem.

This doesn't have to be a blessed runtime in std, but could be just a set of common interfaces (basics like AsyncRead, sleep, and spawn), so that async crates don't have to directly depend on a specific runtime.
