I regularly see the phrase "all Xs are Ys, but not all Ys are Xs" in teaching material. Even material for children!
I have to re-read it every time. I very much prefer "Y is a more general category than X" or "X is a subset of Y".
Do people find this phrasing helpful, or is it poor pedagogy?

It's weird that GitHub shows time since the last commit, but not time since the first commit. It's a nice way of seeing how mature a project is.
