In a particular project I deal with, I'd say that half the table iteration code is complicated, with stack use heavily commented. And many of those complicated cases have nothing to pop at the end of the iteration, so the for-form would just look strange.

I'd say the while-from is idiomatic, and the consistency of its use makes those complicated cases easier to understand.
