If I try to reproduce the solution in https://github.com/marshmallow-code/marshmallow/issues/2297#issuecomment-2284962125 with `partial` instead of `dateformat`, it fails. I guess this is because the `__init__` at https://github.com/marshmallow-code/marshmallow/blob/dev/src/marshmallow/schema.py#L204 is missing the `partial` keyword.
