Sounds like a plan for a next generation cloud provider. They all have internal state about your account and what's running there; they just don't really expose it in a standardized way. Nor do they provide standardized ways to update that (other than a lot of cli tools and REST APIs).

We keep coming up with these layers of abstractions around stuff that at the bottom is essentially already stateful but just not in a useful way. Doing it right from the ground up might help. Of course, left to the usual suspects, this would just turn into another Frankenstein blackhole of devops time. The usual suspects are billion dollar corporations that thrive on layers of complexity.
