Does a threaded BB really solve the problem of poor manufacturing techniques and tolerances on (some) CF frames? Since the BB is built around around the shell on CF frames, rather than the shell being a strong load bearing joint as on welded frames, it still seems like there is plenty of opportunities for manufactures to use weak shells that will cause the cups to become misaligned over time. Just because the BB threads in doesn't mean it's magically stronger, and better aligned is what I'm getting at.
Not hating on threaded BB's though; I went out of my way to get a T47 BB on a steel gravel bike so I could run a 30mm spindle with the bigger bearings and flanges that T47 allows.
