Writing an API that scales from quick PoC to MVP to serious production is in my opinion a problem space that is mostly not explored. We've tackled this with iommi (https://docs.iommi.rocks https://docs.iommi.rocks) with deep customization while at the same time having super fast PoC. We are not satisfied with the performance yet though, but at this point it's good enough for most uses.
