Welcome to enterprise computing, and to the world of zombie software management.

Other OS vendors can carry decades of cruft and baggage for reasons of compatibility with older applications, and that really slows down development, and the testing costs scale upward for whatever you can't retire. You end up implementing the Windows XP box in Windows 7, the pain that has been IE6 replacements and upgrades, and various other forms of API and run-time and source-code compatibility, and translators.

Some of this zombie software lives on ten and twenty years past expectations, and longer.

Apple throws features and hardware under the bus when it gets in the way of their skating to where they think the puck will be.
