The comment chain you replied to said it's a stable and ubiquitous arrangement. You're not trying to argue it's stable or even that it's an arrangement - you're just arguing it can be found within a larger structure. It's as if someone said cliques and anticliques aren't good designs for computer networks, and you said yes they are, because every network of a certain size contains a clique or an anticlique by https://en.wikipedia.org/wiki/Ramsey%27s_theorem - that may be true but it's incidental.

It's also as if someone is saying that Java isn't best at functional programming, and you pointed out that yes it is, because look at all the functions calling other functions.
