This scandal is not going to be seriously dealt with until the clerics involved with the offense or the cover-up are defrocked, excommunicated, and reported to civilian authorities.

Mercy is extended through the confessional, and that potentially reverses only the excommunication -- the defrocking is permanent and reporting them to civilian authorities is non-negotiable.

Though I suspect such abuse has been extant for, perhaps, centuries, and is irreversible given the entrenchment of clerical recruitment, training, power, and lifestyle.

If a Pope is not going to deal with the issue "en masse", it is not going to be dealt with. Everything then is just so much noise and distraction, including this powerless commission  -- a "long-game" strategy to outlast accusers, survivors, and critics.
