-1. Combining asynchronous code with synchronous code that can cause blocking is never a wise choice.
+1. Minimizing usage of async Rust.
+  Refactor coded as much as possible to be in sync functions, 
+  and have async just be little "router wrappers" for waiting on stuff and feeding it to sync functions.
+  See good discussion at 
+  [Avoid Async Rust at all costs” - comments from experts?](https://users.rust-lang.org/t/avoid-async-rust-at-all-costs-comments-from-experts/105860)
+  .

+2. Combining asynchronous code with synchronous code that can cause blocking is never a wise choice.
     When calling asynchronous code from a synchronous context, 
     use `futures::executor::block_on` and spawn the async code to a dedicated runtime, 
     because the former will block the current thread.
