You are correct.
I assume that all priests know Latin-and that saying/reading the mass in Latin is not beyond them.
So what is to stop any parish priest from offering one mass in Latin per week? There are ususally three masses on a Sunday- early morning, midday and later in the afternoon. So one of them is done in Latin instead of English/Spanish/whatever.
Decent attendance=continuation. Empty pews- your parish doesn't want Latin mass, so you stop.
The IMPOSITON was in stopping Latin masses; giving the faithful a choice in every language but Latin. That drove those who prefer their traditional mass away from the main body of the Church. What's worse, there is a real 'outcast' feel.
I attend Latin mass- and the tiny church that offers it is hard to get to, and always crowded. The children in the family go to Catholic school- and they get grief from the parish priest about not attending mass there on Sundays.
I resent being considered 'schismatic' for preferring what was right for thousands of years.
Why should Latin be considered 'bad', as a language, when any other language is just fine for the mass? Why can't it be offered as a choice- as any other?
Your first assumption is wrong. Most priests these days do not know Latin. Those who know it fall into two categories: they love it, having learned it outside the seminary/ they love it, having learned it IN the seminary and realizing its utility and beauty; OR--they learned it in the sem and absolutely hate it.
Perservere WITHIN the Church and you take the most reliable road to restoration of the magnificence of Tridentine worship. Also, Latin language is not the real crux of the matter. It is the NO promotion of the "presider" as rock star: "Hi, I'm Fr. Bruce and will be your presider today! Hallelujah!", the priest facing the people as though they were worshipping him, the agonizingly heterodox translations into Enmglish, the lack of a sense of the sacred, etc.
I am in the Rockford diocese where Bishop Thomas Doran has told each and every priest that the priest may say the Tridentine Mass without further permission. The bishop has said the Tridentine Mass and conferred confirmation in the Tridentine Rite. Not only is he not a schismatic but he sits on the seven-judge Signatura, the Church's Supreme Ecclesiastical Court in Rome. Also, Latin Novus Ordo Masses have always been allowed.
