It is interesting that HW guys choose the solution which required modification in Linux. The "other system" (could we guess it was MS Windows?) used all bits, so instead telling "change your ways and do as Linux do", they told Linux "you have to change". Isn't that unfair?

All operating systems will need changes to make use of this feature; it doesn't seem all that terrible if asking this particular change from Linux turned out to be the path of least resistance. Especially since Intel is actually doing the work to effect that change.
