Ask HN: Does Dvorak keyboard offer anything to the phone typist?

A native Dvorak keyboard has finally become available on iOS. Does it offer any of its supposed ease-of-use advantages when used in the one/two finger/thumb patterns that we usually use on our phones?

I've always thought it would be cool to learn Dvorak, but was too lazy to print new stickers for my keys on my normal full keyboard. I've turned Dvorak on on my iPhone and I appreciate that all of the vowels are on the center line. With time, I could see how I'd learn this. But I'm not sure if the "reduced reach/movement" translates from full handed keyboarding to just thumb keyboarding.
