I don't have anything to contribute, I just wanted to say the Automation API is neat and seems really useful. Particularly enjoyed reading this example repo:

halloumi: a prototype of a heroku-like tools that shows what sort of powerful abstractions can be built when infrastructure is just another part of your application code.

Personally I'm really excited for automation api in typescript. There are a lot of possibilities for building app frameworks with closure serialization support.

Definitely looking forward to that as well -- not particularly handy with Go myself, but really comfortable with TS, so that would open a lot of doors for me = D
