I don't quote understand the above.

If every "for" usage can be done with "while" and that "while" is the
preferred way, why not ? As I said, the problem is that "obvious"
really is subjective in many case. And if it really is obvious, it
really is obvious and I doubt there would be that much disagreement. I
am a left handed and any time I use something that is designed to be
right-handed, I have the same feeling too, luckily there isn't that
much thing in real life.
