Any reason not to consider pydantic as the next step?

Every time I’ve used Pydantic I’ve found it to be a tonne of friction. The developer ergonomics just don’t seem right.

These days I use attrs and cattrs, and I’m much happier. Everything feels a lot more straightforward.

attrs is what Python’s dataclasses were based on, but they kept on improving it, so attrs just feels like standard Python with a little bit extra.
