I agree there should probably be more choices in footstrap placement, including 3 strap options and angle of straps. And I agree it is more natural to have the front foot angled forward.
However, in a single strap placement, you seldom are putting your foot straight in. In fact, notice in flyboy's video he is not putting his foot straight into the strap on his 3 strap setup. Instead he is putting his foot parallel to the rail.

That type of stance would not be natural for me and I would end up with my heel in the water on that board with that strap setup and with my preferred stance.
Different people like different things and have different bodies, water conditions, board, and styles.
There is probably a little too much following the trend and not enough doing your own thing in the sport. That sort of behavior is not limited to kitesurfing.
I happen to use two straps. I find that my foot position is the same, including my foot angle, as when I don't use straps. In fact I picked the strap placement by riding the board without straps and i have set the strap loose enough to allow freedom to rotate my foot.
Notice my front foot is angled to the front.

But I do agree that there should be more productions boards with three strap options but they obviously are going to increase the price. Honestly, even finding boards with strap inserts is getting harder to find as we go into the latest trend of strapless surfboards.
Anyway it is all good. Like I said, I have seen guys rip on 0, 1, 2, and 3 straps. I find it interesting to see all of the different styles that kiters have adopted. It is good for the sport.
