Mainly lack of time for anyone to work on integrating it into the system.  It's been on my to-do list for about a year, but never been a sufficiently high priority.  It will probably move up a bit after 10.0 is released.

Having looked at the Apple code, it seems a bit cleaner (although does need some refactoring so that the CPU and OS-dependent chunks are isolated rather than being big tangles of #ifdefs).  

Whichever route we go, we'll need to reimplement some of the helper functions that various personality functions use on ARM.
