I think the Xen Project CI is having similar issues due to using Zuul
and skipping tests causing an empty positive vote.

Not yet. Ideally we want you to run on every change, that gives us the
most confidence in the tests.

But skipping docs only stuff and unit test only stuff makes sense
though, just like how we don't run tempest for those changes.

Now that might not be possible due to hardware costs, or similar, at
which point, we should talk about what things it might make sense to
skip. Your above list makes quite a bit of sense I guess.

If this continues, I'll be in favor of removing commenting privileges for this account and will be hesitant to throw in my support for re-enabling it. Running CI against gerrit comes with serious responsibility for monitoring!
