[REQ] Generate JSON schema form OpenAPI docs

Is your feature request related to a problem? Please describe.

I have to test an API, and right now I would need to test whether the response is conform to the appropriate JSON schema. Now I do not have JSON schemas, so I generate them using several tools in a chain.
But it would be good to have one tool which generates them - from the responses

Describe the solution you'd like

For example the models folder (I use Python, but other languages should have these schemas too, just in folder specific to given language) should contain the JSON schemas of the responses, as they are some kind of models.

Additional context

Note: When there was some some issue in OpenAPI spec, the generator left (did not delete) some JSON schema file, I do not know what state had it, was it good or not

BR,
George

The request centers on the generator, the models folder, and the OpenAPI spec; start by tracing how response models are produced for a selected language. Define completion as generating response JSON schemas in each language-specific models folder and handling stale schema files when the spec is invalid.
