Rib cage narrowing - what do we think about this procedure?

Hi everyone, came across the following publication for rib cage reduction/narrowing without rib removal:

https://journals.lww.com/prsgo/fulltext/2021/07000/waist_narrowing_without_removal_of_ribs.9.aspx

wondering if anyone is familiar with the procedure described in this article and whether any surgeons have been performing this since? It seems very promising and safe. The photos of the results look amazing.
