I've written a Prime minicomputer emulator, and it has these kinds of flags. In my experience, if you don't do exact hardware emulation, there will be some oddball program that doesn't work. If someone posted their program that Apple couldn't correctly emulate, it would cast doubt on their emulation in general, even if this oddball program is the only case in the world where it didn't work. For Apple, I'm guessing that failing to emulate even an oddball program would be an unacceptable risk.
