This is extremely unlikely to occur in practice. Apple is sensible
enough to, in these sorts of circumstances, make these changes
depending on which SDK you're compiling against or, since Core Data
has versioning support now, silently upgrade files upon opening them.
Note that silently upgrading files when opening is the last thing
you'd want in this case. A file saved using FooApp 1.2 on 10.6 should
still work in FooApp 1.2 on 10.5. If you destroy my files so that they
no longer work on 10.5 without even asking me then I'll get upset.
Ben Trumbull specifically stated that as long as FooApp 1.2 targets
10.5,
this scenario won't happen.
