User Mutation Clarification - imagine User having 20 keys, 5 of which are non-nullable (email_verified: Boolean!)

User.graphql

type User = {
  id: ID!
  first_name: String
  last_name: String
  email_verified: Boolean!
}

input UpdateUserInput {
  first_name: String
  last_name: String
}

type UpdateUserPayload {
  first_name: String
  last_name: String
}

type Mutation {

  // I wish I could do this (despite email_verified)
  updateUser(input: UpdateUserInput!): User
  
  // but I have to do this:
  updateUser(input: UpdateUserInput!): UpdateUserPayload
}
