The only thing I could think of, and even this is a stretch, is that
having dropped PowerPC with Snow Leopard, they don't need to maintain
bit-level compatibility with programs over the two architectures.
PowerPC presumably uses proper IEEE-754 arithmetic.  But, it seems
like that would have been quite hard to establish, given that x86
needed to use x87 calling conventions.  And, if one did establish it,
keeping IEEE-754 arithmetic on x86/amd64 would be ever so much nicer.
