Here in lies the problem. Everybody is told to get adj control arms to fix their castor, but if you put your castor back to stock then your pinion angle is out and you'll get vibrations. The only way to dial it in on a lifted vehicle so you have perfectly stable steering and perfect drive-line angles is to cut and re-weld the C's and control arms mounts in new positions. Most people don't do this unless they are really into custom vehicles though. The aftermarket axles ProRock etc are built with the lift in mind therefore all the mounts and C's are in the perfect or near perfect position so there is good steering with no vibrations due to pinion angle.
Too many people get the adj arms and dial in their castor and don't even think about their pinion angle. I see lots of bad info given out on the forums, it's no wonder people have bad vibrations and steering because they expect everything to be solved with one part and ride perfect afterwards

If you have a bigger lift and want everything perfect, yes. That's why like the poster above mentioned people do it when they rebuild axles or buy aftermarket you pick your height so they can have everything welded up properly. We have to do this for the rearend of every airbagged truck to do it right. You set all mounts for ride height. This is no different for 4x4s except most people just deal with it as it's that much extra work.
