Important Factoids

For instance incorrectly setting a consul config service router or ingress gateway configuration with services that do not have the corresponding protocols is a hard error. But there exists no mechanism from TF to be able to query details about consul_config.

Since config resources are optional, I'm not sure how that'd be handled here. TF data conventions don't always play well with empty return results.
