We don't can sealed core schemas in root level, because in draft-06 don't support additionalProperties: false and allOf properties together.
JSON Schema org work on this problem and it's soon resolved.
And that's why I suggest waiting draft-07 and draft-08 JSON-schema releases and after then sealed all core schemas in root level.
For close this issue we should be migration all schemas to the new draft.
