I've been speaking with a custom builder on another matter...

Usually distortion happens from welding but is then corrected during post weld machining.."
Yeah, I should say before we go any further that I wasn't being snarky about, "if that suits your personality." I realized after the fact that might have sounded a little pissy. I just meant that some folks could stand the aggravation of the imperfect bike better, and other could stand the aggravation of trying to get it replaced better. Sorry if it came across wrong.
Back on topic, I think round would be a minimum requirement, at least within a couple of thousandths of an inch. But who knows? I wonder when you press the bearings into that shell whether it deforms them (and perhaps the shell too) to make a seal all the way around touching the shell? Or can you still see daylight?
