Strictly speaking, _I_ don't, but _you_ might ;-)

I doubt that the proposed commit log message justifies the claim
"architecturally making more sense" with concrete enough discussion, but
I'll let it pass.

Your log message got much better this time, by hinting that this is a
preparatory step to introduce the rev-cache mechanism.  It is good way to
defend a patch saying that it is not just a useless code churn, but it is
a necessary step to get us closer to a more useful goal.

You have a wrapped line here.  Please check the setting of your MUA,
especially if you are planning to send more patches to the list in the
future.

No need to resend; I fixed this up when applying.

Thanks.
