The Nut fixation was part of the strengthening of the spindle too, the earlier version (slightly narrower) was also hollow clear through.

Not only did it flex more, it left Laurent in the lurch! He lost the 1982 Paris-Tours race because of this. He had a substantial lead and a tailwind when his BB broke. This pic says it all.
The OP's BB won't, because it's solid. Legend has it that Laurent Fignon's high-profile crash, snatching defeat from the jaws of victory, is why Campag changed from hollow to solid, but I don't know if that's true.
