My point was that neither the zero page problem nor the upgrade problem
are solved by addressing the hint bits problem. They can be solved
independently, and in my opinion, it seems to make sense to solve those
problems before the hint bits problem (in the context of detecting
hardware corruption).
Of course, don't let that stop you from trying to get rid of hint bits,
that has numerous potential benefits.
