Try to spell my name correctly when responding to me.

Yes, you also wrote
"Then the answer to the potential null+-1 being valid is simple,
mandate in the next standard that the 0+-PAGE_SIZE be premapped as
sealed no rwx pages. That resolves the problem completely. They don't
need to have anything mapped to them, just that they be mapped as
invalid."

which doesn't solve the problem "completely", or in fact, at all.
