thanks for bringing this to our attention - in 9.0 EE you can already find a corresponding change, where camera permissions are handled per sample. We plan to bring this to PE with 9.2 to make your and other developers life easier.
Thanks again for the feedback - very much appreciated!

Perhaps add those lines somewhere else, so one can simply drag e.g. WikitudeCamera + ImageTracker into a scene and then it works.
I'm referring to these lines:
