This is what we have so far: https://varick.io/
We make a ton of MVP apps, and what you're talking about would be amazing! But the reality is we'd never get close to it. Every app focusses on a different audience. We aim to help them reach their unique goal as quickly as possible, which inevitably means a different UI approach for each scenario. It's not worth the effort in trying to automate.
Instead, we focussed on a generating a front-end for admins. It works with APIs so any business logic and security validation is just baked in cannot be by-passed.
