 - Remove `async` and `promise-to-callback` dependencies
   - These dependencies were used internally for middleware flow control.
-  They have been replaced with Promises and native `async`/`await`, which means that some operations are _no longer_ eagerly executed.
-  This change may affect consumers that depend on the eager execution of middleware _during_ request processing, _outside of_ middleware functions and request handlers.

     - In general, it is a bad practice to work with state that depends on middleware execution, while the middleware are executing.
