If I'm given a chance to develop, I would start with the last part of the sentence that might sound subjective. For example, the 'Future' class in 'concurrent.futures' exposes a method named 'result' to collect the result of a task. In contrast, the 'Future' class in Asyncpal exposes a 'collect' method and a 'result' property.

The stdlib's pools only grow in size and do not shrink, making them non-elastic. Therefore, I would not want to keep them alive in the background for sporadic workloads [1].

Discussions on 'concurrent.futures' vs 'multiprocessing.pool.Pool' highlight that each has unique features. While 'concurrent.futures' is the modern package, it omits some niceties found in 'multiprocessing.pool.Pool'. For example, 'concurrent.futures' has only one 'map' [2] method, which works eagerly and therefore not suitable for very long iterables [3][4]. However, I acknowledge the superiority of 'concurrent.futures.Future' [5] over 'multiprocessing.pool.AsyncResult' [6] because tasks cannot be cancelled with the latter (among other things).
