I don't know much about Japanese, but in written Chinese, the stroke order is less likely to be consistent. One of the challenges for early leaners of writing Chinese characters is to "get the stroke order right", and many, even sufficiently educated adults could struggle getting all orders right. Also, writing Chinese characters in cursive often requires different stroke orders for the same character due to aesthetic reasons, and the boundary between print and cursive style in hand writings could be very blurry. Therefore, I could see stroke-order becomes a very noisy, inconsistent and less reliable input.
