How would you do `@shareable` + `@requires`?

Schema Design

Hi! We have a use case that super-simplified wants to look like the following

Schema A

type ResponseConfirmation @shareable {
  """A string to display in the UI thanking the user for their response."""
  confirmation: String

  """A copy of the submitted answer so the UI can confirm."""
  submittedAnswer: String
}

type Mutation {
  submitSurveyResponse(answer: String!): ResponseConfirmation
}

Schema B

type ResponseConfirmation @shareable {
  confirmation: String @external 
  submittedAnswer: String @external 

  """Using a fancy AI model, calculate a 'helpfulness score' rating based on the submitted answer"""
  helpfulnessScore: Float @requires(fields: "submittedAnswer")
}

Query

mutation {
  submitSurveyResponse(answer: "foo") {
    confirmation
    submittedAnswer
    helpfulnessScore
  }
}

^ obviously this doesn’t work because ResponseConfirmation is not an Entity! (@external/@requires only works with entities afaik.)

We could give it a fake id: uuid() field or something and make it a “fake” entity – (and not worry about the impacts it might have to normalized caching on clients :grimacing:)

This is clearly a hack - can we do any better?

Thanks!
