Good to know that using Fragment#setRetainInstance to reuse (Web)Views is not supported. Since it is actually working for my simple scenario, I was looking at continuing to use it, and it potentially might have run into issues at some point in the future.
Will look at using android:configChange="orientation". The problem with this approach is that I am also using a GLSurfaceView (besides the WebView which needs to be reused) which cannot deal with orientation changes. I will have to destroy the old GLSurfaceView, and create a new one for the new orientation in Activity#onConfigurationChanged. Since the GLSurfaceView rendering happens on a separate thread, it might be a bit tricky to get this right though.
