So the question is really how the hardware treats writes to non-existent registers. My guess would be that they are simply not recorded, and if that's the case it doesn't matter what we do. And doing an unconditional AND is faster than doing a bit-test followed by a conditional branch.
Hardware ignores writes to non-existent registers. Sometimes non-existent registers are taken into use in future versions, though.
