I actually did the opposite recently and replaced reqwest with ureq and managed to drop async and tokio altogether and greatly simplify my library. As a newcomer to Rust I kept getting pointed towards reqwest and tokio when ureq is far simpler.
Without knowing what your library does, it's hard to tell if the simplification benefit is worthwhile when traded off against the lack of usability from apps which should not be blocking worker threads. Could well be, but overall I'd just use Tokio and Reqwest (which has a module exposing a blocking API, even!)
