Yes, but this comment[1] makes me nervous:

However, Node v7 is based on V8 54, whose async/await implementation has some bugs in it (including a nasty memory leak). I would not recommend using --harmony-async-await in production until upgrading to V8 55; the easiest way to achieve that would be to wait for Node 8.

Also, I'd rather not use a non-LTS version in production since I don't want to have to keep track of changes. Most of the stuff I maintain sits untouched for months between releases; I think there might even be a few things still running on 0.10.
