Yes, its only a slight over-generalization to say that free projects 
have no obligation to existing customers and they usually prefer 'new 
and different' development to boring backward compatible support work.

Even though RHEL isn't a free project, there's only so much they can do 
to reconcile the wild changes in the code they include.
