You've hit the nail on the head about my reservations.

Regarding your recommendation, were there any libraries that exist already?

Otherwise, I assume that you mean:

1) write some code to derive a CRUD/RPC OpenApiV3 Spec from some data-at-rest spec/JSON Schema other (e.g. RDBMS Table)

2) generate endpoints conforming to that spec and wire it to persistence

3) generate UI components that allow you to drive requests to those endpoints.

4) build something to serve backend + front-end

Those steps look like a low-code system to me?
