Well, I searched the Japanese wiki and found following passage
here: "身体機能の代わりを務める人工骨格や人造臓器は珍しい存在ではなかったが、それを「身体機能の強化」目的 で用いる場合、様々な問題があった。" From what I can gather it translates as "Artificial organs and bones are okay as replacements but what Scaglietti did was way beyond that," implications being that regular cybernetic replacements are commonplace but Combat Cyborgs are no-no. I guess that is the origin of the claim on the English wiki you mentioned.
