It's in beta though. Planning to move ahead and start using it in our team now.

Please file bugs! We only backport major stuff to beta, but this is such an important feature that hearing about things early is even more important than it usually is.
I think I'm going to skip this one until the recently stabilized async-await feature has finally made it in the next version. :)
