At this point we're arguing semantics, which is a futile exercise. So yes, we should just say x, y and z rather than fluffy words like 'production'.
In my experience people who use the words 'production use' are often talking in the context of a system that runs all the time, and that has a team of programmers working on it. In this context there can be lots of x's, y's, and z's that go into 'production', but it always includes "should I be afraid of upgrades?" (roti can confirm or deny in this case.) There's a reason perl and python and common lisp and racket have gone through contortions to indefinitely support bad ideas.
I'm not saying this is a good thing, btw. I think this whole model is wrong. But I'm just one guy shouting at the cosmos, and I certainly haven't seen more than the tiniest sliver of what people do with software.
