There's all kinds of use cases for classes without dataclass. For example, just the other day I wrote a leaky bucket rate limiter class. It uses the __aenter__ and __aexit__ methods to do things in async with blocks. I love dataclasses, but there needs to be a compelling reason to break everyone's code and the reason can't just be "I don't want one import and one decorator".
