This is not necessarily true. It depends on whether the rom image is
different or not and there is no way to tell up front. So if a0 has same
rom image as a1 the firmware is compatible and no distinction is needed.
This tends to be the case for chips that only change the digit and not
the letter in the chip revision. Anyway, I do not know if a0 has
different rom image, but the a0 was never sold so there is no harm in
keeping it as is.
