Uh, no. One reason the blade of the foot is so popular as that it's easier to hold the foot in that position than it is to pull the toes back and strike with the heel. Speed and height have nothing to do with it.

All about the heel, baby.
I'm not advocating the blade, but that's just plain untrue. Holding your foot in a proper blade requires a lot more effort as your toes and ankle have to mold in two different directions instead of just pulling everything up/back towards your shin.

Based on the number of students I've had to correct because their foot naturally turns to the bladed position on extension, I'm going to have to disagree. I'll give you the caveat of "proper blade" though.

I walked into a karate place recently. Through the course of talking MA, lineage, history, playing the "do you know....?" game, and other stuff he asks me:
"Can you do this?!"
He then slams a back two knuckle strike (I guess it is just called a backfist) into a wall HARD as hell.
I was surprised and of course could not do that without breaking my hand.
But then later I thought, of course I could do that.
All I had to do was use a hammer fist. Same affect and delivered the same way but I don't have to subject my hands to abuse for years to attain it and waste countless hours where I could be training more usefull skills. Just had to change my hand form.
I think most of us are in agreement on that part. The big question is why the hell it's done. It's one thing when beginning (or lazy) students do it and we correct them, but some places actually TEACH it that way.

Anyone with even a layman's knowledge of physics would laugh at such a discussion.
You know, that's something that bothers me... when people say things like this are "outdated." I've seen other people say it about, for instance, chambered blocks. The human body hasn't changed significantly since these blocks and kicks were devised. If they aren' t useful now, they never were.
The point is, back then they also used a rock to kill someone, for most of the time humans have evolved and try to be sophisticated, using knifes and guns nowadays.
Some of those techniques or to be more precise the way they are/have been practised have been modified either for teaching reason or pure cosmetic effect.
Or people just striped down the technique to its "core" using modern science and profound knowledge of human anatomy.
It is a part of the "aliveness" of a MA that it changes and adapts...
