I'm not sure it's a given that OMF requires a licensing fee and if it does, whether that's a significant fee. Besides, Apple already provides OMF via Logic. Avid and Apple also have a current (new) relationship, because Avid licenses the ProRes codec from Apple. If Apple were to do anything, they should probably go with AAF since that's the current standard with ongoing development.
The downside of third parties is that Apple takes no ownership of the features. We've already seen how this has burn the AD ProExport plug-in and others. Third party developers are often quicker to respond to issues, but they also have a smaller development team and a smaller beta tester pool (although I don't think Apple does enough beta testing of these products compared to other manufacturers.)
