Miryoku does the same thing but the orientation is flipped vertically with the 0 below the center column, which is how it’s done on a full sized keyboard as well.
Miryoku basically has the numpad, which I still think is dumb to be quite frank since the numpad was only made like this for archaic historical reasons.
Having the 0 on the thumb is quite a good choice though. As long as one doesn't have to move outside +-1 of the home row of keys (like one has to with numpad).
