This certainly is akin to what I had in mind, and looks really great. A couple of thoughts:

1) Ideally the framework is polyglot (Go seems sensible though)

2) I wish they had queues/events that were wired up to functions

3) Not sure if using autoscaling k8s services under the hood as opposed to serverless functions is the right choice

4) A bit too opinionated on DB/Auth (maybe I don't want to use Postgres)

5) With all of the above you could get really great end-to-end integration tests as unit tests that I don't see them taking advantage of
