I mean it has variable names, configurations, documentation, a file extension and lots of code and a history behind it, so the strange thing to me is trying to suggest a replacement phrase as if you don't know what it is, acting like it's some high-brow language used in a blog to look smart, complaining about how this makes it less accessible (paraphrasing a little), then rolling back saying you dabbled in Nix and acting like you know what it is.
But then, you do you.
The part you seem to deliberately miss is that what is obvious to people deeply invested in Nix is not obvious to anyone else.
I for one can't trace the train of thought that is going from "intermediate build artifact" and somehow arrives at "derivation".
I found out just enough about Nix to reject it. My take is still informed, I simply didn't buy its pitch.
