Ya the only way I could ever see this being maintainable is if it's declarative. It takes a tremendous amount of boilerplate and configuration to perform what comes down to a one liner in any functional language or a formula in any spreadsheet. I think I would be more interested in a transform that converts a series of goroutines to lambda functions or something.

You know, architecturally, at application level no one wants to deal with this but devs orchestrate nightmarish dependencies for deploys and hit 'endpoints' with aplomb in service architectures with only a playbook or data blueprint to follow. What's the point of fighting this?

Let the kids play.
