[Schema Inaccuracy] example seemingly used as a pseudo-discriminator

[masklinn]

.components.schemas.environment.properties.protection_rules (and some other places I think) is defined as:

    "anyOf": [
      {
        "type": "object",
        "properties": {
          "id": { "type": "integer", "example": 3515 },
          "node_id": { "type": "string", "example": "MDQ6R2F0ZTM1MTU=" },
          "type": { "type": "string", "example": "wait_timer" },
          "wait_timer": { "$ref": "#/components/schemas/wait-timer" }
        },
        "required": [ "id", "node_id", "type" ]
      },
      {
        "type": "object",
        "properties": {
          "id": { "type": "integer", "example": 3515 },
          "node_id": { "type": "string", "example": "MDQ6R2F0ZTM1MTU=" },
          "type": { "type": "string", "example": "required_reviewers" },
          "reviewers": { ... }
        },
        "required": [ "id", "node_id", "type" ]
      },
      {
        "type": "object",
        "properties": {
          "id": { "type": "integer", "example": 3515 },
          "node_id": { "type": "string", "example": "MDQ6R2F0ZTM1MTU=" },
          "type": { "type": "string", "example": "branch_policy" }
        },
        "required": [ "id", "node_id", "type" ]
      }

The examples associated with the type property seem to be used as discriminator values (although without that being spelled out explicitely anywhere).

I understand OpenAPIv3 has a discriminator feature for exactly that use case.
