From my source material in my class on Trent:
“One peculiar note on Canon 9 is that it repeated, in the negative form, “If anyone says…that the Mass should be celebrated only in the vernacular…let him be anathema.”
With these few words, the council decreed simply that Latin was legitimate. Despite what is often attributed to Trent, it certainly did not condemn vernacular liturgy or rule it out as unfitting. “

The Canons and Decrees of the Council of Trent – Rev. H. J Schroeder – 1978
Perhaps that is a way to parse the language, but the 500 years after was not interpreted that way. Similar to Vatican II, where the constitution on the liturgy specifically calls for Latin to be taught to the faithful and that it is to be the primary language of the Church, the practice since then is clear Latin is over - I’ve been to at least 100 parishes due to travel and never heard a word of it, unless it is a Traditional church that has a Latin mass on its schedule.
