The idea was to offer _some_ sort of table on new CPUs, instead of

Eventually Intel stops changing those model specific index values in
future CPUs and puts them into architectural perfmon, for
fundamental stats like L1/LLC cache statistics.

In that case defaulting to the latest (known) enumeration might work
out to be just the thing used by all future CPUs.

So this is a subtle hint ;-)
