They do this. Basically everything runs straight through wechat, as if the facebook appstore hadn't lost relevance. Wechat is the api in most cases. You can even go to court on it.
It is still unclear to me how a Weixin ID corresponds to a government issued ID and how an app would know that a user is a minor.
The Chinese mandate you linked to describes the same rules as elsewhere, but there is no indication of how they would be implemented. Does a "real name" policy mean that an login is tied to a government ID? Or does it just mean what Facebook does to make users more valuable to advertisers?
I'm astounded that there is so much gossip about this and so little evidence.

Yes, as someone who lived through the Cold War and has been studying Mandarin for a few years, I cannot help but see parallels in how everything about China is being muddled.
