That cuts both ways.  For brand-new reviewers who starts from v2
without ever seeing v1, and when the two iterations are far apart in
time, it may be true.

But reviewers who helped you with earlier rounds hopefully know what
they saw and commented on, and keeping the same base would help them
to see what is different in the updated iteration, without having to
see distracting changes in the surrounding area brought in by using
the newer base.

To me, it does not make too much of a difference (unless it is
clearly a fix for a grave issue that should eventually merge down to
older maintenance tracks, and this one is clearly not).  If you
rebase, I would double check your rebase by rebasing the new
interation back to the old base and then merging the new base in to
see how the result compares, like I just did this time, before
replacing the topic with the application of patches on the updated
base, so it is a one-time extra cost to me, but other than that,
what I do would not change all that much and it hopefully will make
it easier to queue later iterations.

Thanks.
