It doesn't matter, which is why China (the country) isn't putting weight behind it. There are hundreds of non-Chinese companies with a specific language for their systems. It's completely incomparable to things that China the country does care about, such as the aforementioned mobile OSes. Of course they'd rather the languages and everything else is Chinese-controlled, that's trivially true. But priorities make all the difference, and this one is incredibly low as so to be a waste of time to even mention until everything else is in place.
