Mutation.Field ignores required=True

[chanind]

I recently upgraded from graphene 1.4.1 to 2.0.1, and after the upgrade all mutations are now ignoring required=True. It looks like this is because only name, description, and deprecation_reason are passed through to Field (https://github.com/graphql-python/graphene/blob/master/graphene/types/mutation.py#L80). Is this intentional behavior? If so, what's the workaround?

In the meantime I created the following base Mutation class to fix this issue, but it's hacky and I would love to not need this:

class Mutation(graphene.Mutation):
    @classmethod
    def Field(cls, **kwargs):
        return graphene.Field(
            cls._meta.output,
            args=cls._meta.arguments,
            resolver=cls._meta.resolver,
            **kwargs,
        )

    @staticmethod
    def mutate(*_, **__):
        raise NotImplementedError('Overwrite me!')
