### Extending to Additional Languages

The design for the C++ generator should apply to other languages, and the
underlying generator framework (the model and controller) try to be agnostic. In
fact, some elements of the C++ design could be formalized (such as the
rendering/view framework) or re-used (e.g. `cpp:Renderer` could likely be shared
with C and Java as a common C-style language renderer base class).

# Separate OpenAPI Schemas for Input and Output or Not

When using **Pydantic v2**, the generated OpenAPI is a bit more exact and **correct** than before. 😎

In fact, in some cases, it will even have **two JSON Schemas** in OpenAPI for the same Pydantic model, for input and output, depending on if they have **default values**.

Let's see how that works and how to change it if you need to do that.
