Thanks for your feedback. My experience with code generation from an OpenAPI spec wasn't that great, to be honest. The comments about performance are based on earlier experience with a similar scenario in which code generation _did_ improve performance. Mostly in that the generated code was "de-convoluted" to such an extent that the JIT could actually do its work. I'm expecting a similar thing here, especially with JSON serialization/deserialization, because of the heavy amount of reflection involved: The generated code would then no longer use reflection, but access fields and methods directly, and can therefore be optimized by the JIT.
