ofQTKitPlayer on OSX 10.6?

I have the code in ofConstants.h from:

  
  
//for 10.7 and 10.8 users we use QTKit for 10.6 users we use QuickTime  
			#ifndef MAC_OS_X_VERSION_10_7  
				#define OF_VIDEO_PLAYER_QUICKTIME  
			#else  
				#define OF_VIDEO_PLAYER_QTKIT  
			#endif  
  

to

  
  
//for 10.7 and 10.8 users we use QTKit for 10.6 users we use QuickTime  
			#ifndef MAC_OS_X_VERSION_10_7  
				#define OF_VIDEO_PLAYER_QTKIT  
			#else  
				#define OF_VIDEO_PLAYER_QTKIT  
			#endif  
  

Now ofQTKitPlayer in the osxHighPerformanceVideoPlayerExample works on my OSX 10.6 machine! (And I guess it uses QTKit right?)

So I wonder why the choice to use QuickTime for 10.6 users instead of QTKit was made, since it seems to work?

I see an issue on GitHub that seems to explain why: https://github.com/openframeworks/openFrameworks/issues/1628
Apparently because QuickTime works fine on 10.6. But I understood QTKit is a lot faster (and so it seems to be indeed).

So I wonder, why o why?

Thanks!
