@deprecated As of version 1.119, without a replacement. All features that have been
  controlled by a compatibility version in UI5 1.x will abandon their legacy behavior,
  starting with the next major version. In other words, they will behave as if compatibility
  version "edge" was configured. Due to this, no more access to the compatibility
  version will be required starting with the next major version.
