It doesn't matter, really; it's still the wrong thing to do, for the
same reason it's the wrong thing in -- for example -- ACPI, which has
similar "cleverness".
If we want to have a "Linux standard CPUID interface" suite we should
just put them on a different set of numbers and let a hypervisor export
all the interfaces.
