Not OP but I don't imagine that would be very useful. The input method is completely different, so the muscle memory is completely different. Switching from Qwerty to Dvorak on phone just means you have to re-learn touchscreen typing all over again as well.

Also while Dvorak is objectively better for physical keyboards, Qwerty is objectively better for swipe touchscreen keyboards, for similar reasons to why it was better for typewriters. The more space between common character pairs, the better swipe keyboards word prediction works.
