Yes this makes sense. However, if you get the WhiteLine, Megan racing or Godspeed (4) link for the rear, it will reduce the stress he is talking about. I would recommend one of the (3) anyway to ensure you get the proper rear alignment after all the work is done.
Without a 4 link, I think you are going to wear out rear parts quickly. You may want to check out some of my products as well.

Sway bar bushings, rear sway bar reinforcement brackets, and a transmission mount insert are all appropriate for a lifted vehicle.
