What do they want async for? PHP's purpose is to run once to generate one HTTP response - they'd already forgotten this by inventing frameworks, but adding async seems to especially have forgotten this.
PHP already had curl_multi_perform which is very useful for running child tasks, but I'm not sure you need much more than that.
