They are not 'stubs'. They are vehicle barriers. Benches would block north-south circulation here. Maybe a few are warranted, (so that you don't block too much north-south movement) but there may be enough furniture in Nathan Phillips Square to satisfy typical demand when all is said and done. You don't know whether or not that will be the case yet, so it's a bit early to label it madness, stupid, and useless.
