At least part of it is trying to save people work, I imagine. "That's a cool tool, but there's an existing, well-supported one that already solves those problem."

Of course, the problem here is that Nix may be similar to this language, but they solve different problems. So I imagine the writer is just mistaken, and it comes off as one-upsmanship.

Fair enough regarding tone; unfortunately too late to edit (man, I wish they’d increase the time limit on that)
