⚠️ This PR contains breaking changes. Normally you should avoid that and make
your consumer backwards-compatible (meaning that updated consumers can still
accept old messages). There are a few exceptions:

• If consumers already require these invariants in practice, and you're
  just adjusting the JSON schema to reality, ignore this warning.

• If you know what you are doing, this change could potentially be rolled out
  to producers first, but that's not a flow we support.
