Not in this patchset...
It is a possible "cheap" (but less accurate) alternative to the
tracking introduced in patch 4. Or can be used in more advanced
implementations of multi-processor GRUB, but not in this patchset.

So, it can be removed from the patchset; I added it so that people can
see all the possible alternative utilization tracking strategies.
