     Setting after startup does not work for most runtime flags, but we
     could add an option to print setters for ones which do:
     void set{{feature.name}}Enabled(bool isEnabled) { RuntimeEnabledFeatures::set{{feature.name}}Enabled(isEnabled); }
     If we do that, we also need to respect Internals::resetToConsistentState.
