I believe the Congregation for Divine Worship has some interesting words on the subject:
Redemptionis Sacramentum
On certain matters to be observed or to be avoided
regarding the Most Holy Eucharist
[12.] On the contrary, it is the right of all of Christ’s faithful that the Liturgy, and in particular the celebration of Holy Mass, should truly be as the Church wishes, according to her stipulations as prescribed in the liturgical books and in the other laws and norms. Likewise, the Catholic people have the right that the Sacrifice of the Holy Mass should be celebrated for them in an integral manner, according to the entire doctrine of the Church’s Magisterium. Finally, it is the Catholic community’s right that the celebration of the Most Holy Eucharist should be carried out for it in such a manner that it truly stands out as a sacrament of unity, to the exclusion of all blemishes and actions that might engender divisions and factions in the Church.[32]
[14.] “The regulation of the Sacred Liturgy depends solely on the authority of the Church, which rests specifically with the Apostolic See and, according to the norms of law, with the Bishop.[34]
[17.] “The Congregation for Divine Worship and the Discipline of the Sacraments attends to those matters that pertain to the Apostolic See as regards the regulation and promotion of the Sacred Liturgy, and especially the Sacraments, with due regard for the competence of the Congregation for the Doctrine of the Faith. It fosters and enforces sacramental discipline, especially as regards their validity and their licit celebration”. Finally, it “carefully seeks to ensure that the liturgical regulations are observed with precision, and that abuses are prevented or eliminated whenever they are detected”[37]. In this regard, according to the tradition of the universal Church, pre-eminent solicitude is accorded the celebration of Holy Mass, and also to the worship that is given to the Holy Eucharist even outside Mass.
[18.] Christ’s faithful have the right that ecclesiastical authority should fully and efficaciously regulate the Sacred Liturgy lest it should ever seem to be “anyone’s private property, whether of the celebrant or of the community in which the mysteries are celebrated”[38].
[28.] All liturgical norms that a Conference of Bishops will have established for its territory in accordance with the law are to be submitted to the Congregation for Divine Worship and the Discipline of the Sacraments for the recognitio, without which they lack any binding force.[65]
In short we have any proposed changes to the Mass must be approved by the Congregation for Divine Worship and approved before it can be done validly…
As Cardinal Arinze has said in
adoremus.org/1003Arinze.html
“There has never been a document from our Congregation for Divine Worship and Discipline of the Sacraments saying that dance is approved in the Mass.”
