Seriously request Wubi Xing input method be built-in in ISO for Chinese users?

Why Wubi xing input method has NOT been built-in in ISO till now, esp for iPad Chinese users?

Since iPad designed and positioned as a productivity tools/devices, however for a large/considerable number of Chinese users, they used to use Wubi input method, besides Pingyin input method.

For Wubi input users, if we can use Wubi on keyboard cover with an iPad, which is much much higher efficiency than Pingyin input method.

However, currently Wubi input method has NOT been embedded/built-in as an original input method in IOS, as Pingyin has been now. Because Wubi is not an original built-in input method in IOS, which means it cannot be used

on keyboard cover for iPad.

So, I seriously recommend/request Apple can consider to embed Wubi input method in iOS, which will obtain more Chinese users.
