Yes, exactly. The reason why monadic concurrency libraries such as Lwt and Async is that the OCaml language does not support concurrency natively. If it did, we would have built something similar to the `ocaml-aeio` library.

Btw there is a modern instantiation of `ocaml-aeio` called `eieio` [1] which supports Linux's io-uring. Eventually, this will be extended to support all the modern I/O stacks on different platforms, and also support performing I/O on multiple cores.
