I don't have any issues with async loading. I'm just saying that I believe what you are referring to when you say the React team is working on an official async pattern is not actually async loading, but async rendering.
At least every time one of their members said the word async in the last couple of weeks/months, it's what they referred to, and it's a completely different (and unrelated) thing. I can't read your mind though, so I'm just guessing.
