Note that while this release changes the *protocol* to be incremental, Istio does not yet send perfect minimal incremental updates.
      However, there are already optimizations in place for a variety of critical code paths, and this change enables us to continue optimizations.
      
      If you experience unexpected impacts of this change, please set the `ISTIO_DELTA_XDS=false` environment variable in proxies

    We used to set this only for packages that had manual supersource. That
    worked everywhere that I know of except for one place: when running the GWT
    util.concurrent tests under Guava.

    The problem is that GWT responds poorly to two .gwt.xml files in the same
    Java package; see https://goo.gl/pRV3Yn for details.
