Problem is it that it self reinforces and before you look every little function is suddenly async.

The irony is that it is used where you want to write in a synchronous style...

Yep, this is my biggest gripe with explicit async, all of a sudden a library that needn't be async forces me to use async (and in Rust forces me to use their async implementation), just because the author felt like async is a nice thing to try out.
