I haven't done that procedure yet to a stock 12 bolt and we've put some power and abuse through them. Not because I don't want to, just haven't done it.
It is good insurance and if you have the ability or the means, I'd suggest it.

The only time I've seen the tubes twist is in a leaf spring application, on a stick car, and the pinion just goes straight up and slams the floor, lol.

I've never seen it happen in a coil spring application, likely because the control arms do a pretty good job of holding things in place.
