Well, I did some testing and you are wright, but there's problem. OnLayoutChangeListener is Android thing since API11+. I don't know if Cordova still supports Android 2.2, but surely still supports Android 2.3. So, onSizeChanged event for plugin is still needed.
" For onSizeChanged, I think you can use addOnLayoutChangedListener(). onConfigurationChanged seems reasonable though. Filed this as https:// issues.apache.org/jira/browse/CB-7085 (https://issues.apache.org/jira/browse/CB-7085) "
