Taking a very long view here, but I think if anything it will become easier and more widespread, as the technology continues to iterate and the convergence of medicine and AI/robotics continues, the barriers to surgery in places like the developing world will continue to be lowered and cosmetic surgery/body modification will become more routine and accepted/mainstream as it becomes simultaneously less invasive/risky and cheaper.
A somewhat unrelated example, this AI easily beat some of the best doctors in China at tumor diagnosis:

Imagine 20 years from now, a robot surgeon powered by an advanced AI that can implant lengthening nails perfectly around the clock, faster than any human surgeon with a less than .0001% error rate. The economies of scale will make building thousands of these robots economically feasible, akin to building and selling MRI machines, and they would operate for the cost of electricity without salary or 20 years of training. Dr. Paley could supervise a “team" of dozens of these machines, performing hundreds of procedures per day.
