Should CI/buildbots report any errors from `port rev-upgrade`? (I'm not aware that they already do.)
Additionally, is it true that, once CI or a buildbot has built and installed a port, `port rev-upgrade` should never report any errors? If so, should the build be marked as failed if there are rev-upgrade errors? Would others find this behavior helpful? Christopher A. Chavez (who recently neglected to check the result of rev-upgrade before submitting a port update)
