That's exactly why I wrote "It's debatable if this really is a bug". Since it's fair to say that people should just use setCamera.
In general I think it's nicer to always have the same starting state for a game, to prevent weird states that are hard to reproduce because steps are involved that might not even be related to the same project.
It appears that there are more instances in FUZE, especially when it comes to error handling, where you don't always get a clean slate per run. But those cases are harder to reproduce. So although the setCamera behavior might not be related on a technical level (but I don't know that), I was also hoping to make the point about expectation in a broader sense as well :)
