"Just in time" is a great expression. It resonates with me because there is an existing body of knowledge around doing things just in time to reduce waste, and I think that's a lot of the motivation for learning things just in time:
1. You don't invest in learning something you won't use, and;
2. Learning something you will eventually use, but not in the near future, has an opportunity cost: What could you be doing with that time and attention that will produce value now?
I will make a separate comment describing what I think the drawbacks are, but I wanted to focus on my support for your preferred nomenclature.
True, but having had a number of my own musings make the front page of HN, the author must embrace the fact that just because they write about Y , doesn't mean the audience won't pull on a thread and decide the important thing to discuss is actually X.
