Correct, the fact that we don't have APIs with the same name but in different packages makes this less common (although I expect quite difficult to debug if it happens!)

I'm just wondering if we can get the best behavior by default without the developer having to do anything special. That is, the behavior would still be correct (even those edge cases mentioned above wouldn't occur) but when a single FXMLLoader is used to load multiple instances of the same document all the imports are already cached.
