I am interesting in why you think that choice of while vs. for is about popularity?

Surely the choice is made in most cases by the algorithm?
If you have an iterator then you use for.
Of course you can use while instead of for but in code review that will get queried.

Perhaps you think my choice of "popular" had a special judgement about
it. Let's define "popular" in the way that I used it.

--8<---------------cut here---------------start------------->8---
Definition. We say x is more popular than y if x appears more times
relative to y when considered in a sample.

Example. For loops are more popular than while loops in a certain
sample because they appeared 17 times compared to 5 times the while loop
appeared.
--8<---------------cut here---------------end--------------->8---

So it's just a numeric comparison.
