Providing the horse isn't sore and there is a rim of hoofwall around the sole then it's fine.
Cluck can we define what you mean by "rim" because one word can mean something different to different people?
All my hard-working barefoot horses have a "ring" of hoof wall, but not a "rim" in the sense of the hoof wall being higher than the sole callous. At the toe, the callous is higher than the hoof wall, and if it isn't then I rasp it so that it is (a toe bevel). At the sides and in the seat of corn, the hoof wall is perhaps a couple of millimetres in height (at most). I have seen the same lack of hoof wall height in all the really hard working and self-trimming horses I have come across.
In my experience it is positively dangerous to have a hoof wall which is long enough to take the frog out of contact with the ground. The three barefoot horses which I know of who developed navicular spectrum lameness were all like this. (On the other hand some of the soundest and easiest to adapt barefoot horses I have seen had stilts for feet when shod, severely contracted heels and tiny shrunken frogs nowhere near the floor - and those feet are extremely difficult ever to get a weight bearing frog with)
