I really like the idea behind this -- jinja is a lot easier to work with than openapi-generator templates and the java-based generators.

Would you have any interest in incorporating api-client-generation capability into this codebase? I would be happy to put a little effort into transforming the API client and templated API generation from https://github.com/dmontagu/fastapi_client into something that would combine better with this code base. That way, it would 1) have fewer generation-time dependencies 2) an easier-to-work-with templating language, and 3) leverage the work you've already put in for model generation.

But I would also understand if you'd rather keep this repository more limited in scope and targeted specifically around model generation.
