Anecdotal, but I have built from scratch a fairly large OpenAPI-compliant service using the Goa dsl (https://goa.design) and a coding agent and I've suspected for a while that the reason I've been as productive as I have with few blind alleys is that Goa kept the mistake surface pretty constrained. I also like not having the model generate boilerplate, as Goa's tooling does all that so much more cheaply. YMMV.
