Growing library size

According to dive, this library is now 79 MB in my Docker image:

This seems excessive for a Python library, and if multiplied by the number of users, it's arguably a serious waste of resources. Based on just the sizes, client and aio/client are mostly duplicates. Under that both api and models are huge, their __pycache__ are similarly huge. Inside models, functions like _get_openapi_to_dict, _to_legacy_item, _to_legacy_value, _to_openapi_value are basically the same, along with some member methods. Could you please do something to reduce this duplication, and the library size along with it?
