As soon as a coin in the coffer rings the soul from purgatory springs.
I am not a Catholic but one of the more moving and beautiful experiences I ever had was hearing a Latin service for a Christmas Eve one year. I love the small church experience I have on Sundays but there is an undeniable spiritual awesomeness in hearing the priest singing, the choir singing, and hearing the organ echoing in a beautiful stone cathedral.
To take that away from the Catholics who connect to God through it is to me a kind of violation.
All Trent did was codify and standardize the practice which had existed, almost unchanged, at Rome since the 5th century.
Mass done before that had many local variations (pre-Tridentine mass).
True, not all of which were abrogated by Trent. But if you compare, e.g., the Sarum Rite with the Tridentine, you'll find that they are very similar, with a few extra prayers, extra rituals, and extra rubrics in the Sarum rite.
