I disagree. This is a typo fix. The original design was never spec
compliant. You cannot expect the typo fix to explain why the original
behavior is tolerable. That is out of scope and should *not* be required
for this fix.

We cannot expect typo fixes to go and trigger vgic/gic reworks and deep
investigations. This is a wrong expectation now, and going forward.
