Thanks, I did not know about this possibility.

I would guess that these developers would also typically respond quickly
and positively if you point out typos in the commit message. So this
makes the extra round trip less of an issue.
I've only submitted some small trivial patches. As far as I could tell,
Gerrit triggered a full test cycle when I just changed the commit
message. That surprised me and made the reviews more time-consuming,
especially because Jenkins would fail fairly often because of what looks
like heisenbugs to me.

I agree that such tricks are likely to do more harm than good for new
