Ah, I understand now. As a potential user though, I think if the tool worked with the OpenAPI one way or another, I'd be able to mock a service's API much faster. For example, maybe it can ingest OpenAPI and transpile it to your tool's schema. Or maybe your tool's schema could be a superset of OpenAPI. Whichever implementation you choose, as long as it helps me avoid rewriting parts of the config that can easily be inferred from existing docs/schemas, that'd be a huge win.
