Hey man,
When will cc.sys.WECHAT_GAME supporting be added to Cocos2d-JS ?

Currently cocos2d-x 3.16 does not have this feature.
Hope you can understand the importance of this feature. 1 billion people are waiting... Hahaha.
I know this has been supported with CocosCreator v1.8.
But I guess there are a lot of developers just like me using the old version.

sys.WECHAT_GAME = 104;
sys.BROWSER_TYPE_WECHAT_GAME = "wechatgame";
