Hi, I was wondering if there were docs or examples anywhere of configuring other relation tuple effects like intersection, or negation in the namespace configs?
It's mentioned as possible here: <https://www.ory.sh/docs/keto/concepts/relation-tuples#effect-of-a-relation-tuple>, but the namespaces page: <https://www.ory.sh/docs/keto/concepts/namespaces> doesn't give much information on configuring this.

Ah possibly not yet implemented? <https://github.com/ory/keto/blob/master/proto/ory/keto/relation_tuples/v1alpha2/expand_service.proto#L67-L70>

sorry, the docs are a bit pre-mature there
those things will be possible with the rewrites PR currently open and soon to be merged
