Are there different techniques to a reverse tummy tuck?

I’m learning that not all reverse tummy tucks are created equal. Correct me if I’m wrong. One way is to cut a chunk of the skin out and then stitch the open sides together under the breast. I’m thinking that’s what was done on me. Another way is to cut the skin and separate it from the fascia so that it creates a flap, use a progressive tension suture technique or quilting sutures so that the tension isn’t placed on the scar and going to pull the breasts down. Why not always use the latter?
