I agree.

We can't justify to merge as only this patch series although this
doesn't change
any behavior.

After we see the further works, let us discuss this patch's value.

In case of big patch series, it would be better to provide separate
all-at-once patch
with convenience for easy patch and testing. :)

Thanks for great effort. Kame.
