On many stones it is. Whether you can shave straight from a stone has a lot more to do with the individual stone than it does how good a job you do honing. Some stones, the razor just will not shave well until you strop, and others will give a fine shave and not change a lot after stropping. It all depends on how much remnant burr/wire there is. Some stones leave barely any, some stones leave a bit but it is very fragile and just the act of shaving may remove it, and some stones leave a fairly substantial one - those absolutely need to be stropped before shaving.
