`async` spec is finalized and is implemented in Edge 14 (behind a flag) and Chrome 52 (52-54 behind a flag, 55 enabled by default).

We will have to see about object rest/spread. It just got upgraded to Stage 3, so the spec is considered complete, but may not have full test suites yet. Little work goes into implementation until the spec is complete.
