The Holy Week changes are also lumped into this discussion but those were in use before 62, and only affect 3 days, but not the actual mass for the rest of the year.
The Holy Week reform affected more than just the Triduum, hence Holy
Week reform. And not merely "3 days," but the most ancient parts of the Roman rite. Palm Sunday's Mass and Office were hugely mangled. E.g. the Missa sicca removed, procession changed, the Passion narrative was reduced by 40 verses (including the Institution of the Eucharist), the introduction of a temporary "table" and versus populum, etc. etc.
For Holy Monday - Spy Wednesday, each Passion Gospel removed the entirety of the Institution of the Eucharist and Last Supper events. Hence with the reformed Holy Week, the Gospel accounts of the institution of the Eucharist (and priesthood) appear nowhere in the Roman rite whatsoever. And we know from these changes plus the changes on Good Friday that they were removed in order to unlink the Eucharist/priesthood from the Sacrifice of Calvary.
But is it a danger to the Faith? Well, at what point when one removes planks from a ship, does it cease to be useful for carrying cargo across water?
