Presumably because the change of runtime would have required all existing code
to be recompiled to take advantage of it (e.g. for the non-fragile ivars
improvement). That would have required some mechanism for applications and other
code to tell the OS which runtime they require. I imagine it all didn’t seem
worth the trouble to Apple considering how quickly 64 bit Macs have become prevalent.
