If this is about catching oversights and mistakes (as seems to be the
case for the example), having {boot,run}time checks in the kernel is
much more likely to have an impact, especially if there is a helpful
diagnostic.
Otherewise, this kind of requirement, if anything, belongs in the ACPI
spec. If it's in the ACPI spec, having it in the kernel is redundant. If
it's not in the ACPI spec, it will be an uphill struggle to convince
people to implement Linux-flavoured ACPI rather than generic, standard
ACPI.
Thanks,
Mark.
