Baah Ben - I do exactly your cheatin ribs all the time. Why? In the past, no space, no smoker.
For a long period of time I lived in a 500 sq/ft apt, no deck, 4th floor, no options for smokers or grills, no decent BBQ places in reasonable driving distance. So if I wanted ribs, I made them myself in the oven almost exactly as you described. When I lived in Tokyo, if I could even find a 1/2 rack of ribs, I didn't even have an oven. I only had a toaster oven. (ie: definition of effort in futility.)
Under certain circumstances, you do what you gotta do, the best you can do.
I have a house now, a smoker now, but still in the depths of winter in North Dakota, when it's noon and -35, windchill taking it to -65, I'll throw a rack in the oven and maybe, maybe, a quick finish on the grill.
