How can the practice be disordered and damaging if it has the sanction of the Bishop, et al?
I’m going to pay you the high compliment of assuming your question was ironic.
Hmmmm, not everything sanctioned by a bishop is good.
Not everything that is lawful is beneficial. Even popes can make grave blunders. It's clericalism to settle supinely for a "Father knows best" nonchalance even in cases where obedience to lawful authority isn't in question.
The practice is disordered because it cheapens the faithful's reverence for the Blessed Sacrament and the sacrament of Holy Orders, and because it conveys a false idea of what the Mass is.
I call the practice damaging because the results speak for themselves.
