We could, but I don't see much value in that. E.g. we would need to code the
software in a way which also works if the hardware is damaged.

That is possible, but I grepped a bit over the source and in this particular
case we would need to manually audit 2201 registers accesses so that they also
work when the hardware suddenly goes up in flames.

That is totally unrealistic and just fixing this one case doesn't gives us
much.
