Possible shop plan names from GraphQL shop query

[Paul_vd_Dool]

I know the REST API returns the `plan_name` on the shop endpoint from which you can determine the status of a shop. I can find posts that list possible values and I'm looking for something similar for the GraphQL response.

// query
{
  shop {
    name
    plan {
      displayName
      partnerDevelopment
      shopifyPlus
    }
  }
}

// response
{
  "data": {
    "shop": {
      "name": "shopify-shop-slug",
      "plan": {
        "displayName": "Developer Preview",
        "partnerDevelopment": true,
        "shopifyPlus": false
      }
    }
  }
}

I'm especially wondering what the response is for frozen, cancelled, closed or otherwise dormant shops.
Does anybody know?
Is there a way to find out?
