I'm nowhere near as cut as your son, and I felt the difference when I tried a stem extender with a modern-style stem instead of a standard Nitto or such. The rocking of the handle bar when I cranked it was less. I didn't feel the difference was very significant. Plan is to go back to a Nitto based on looks.
Stem flex is a far cry from stem breakage. Well-made parts are able to take literally millions (at least) of cycles of elastic flexing (NOT inelastic) before fatigue begins. Metal fatigue is what leads to fracture. Additional factors include the presence of stress risers due to deep scratches, overly sharp edges, or casting flaws that might cause internal stress risers.
