A lot of people have an idea about the 'Old Mass' that it was so much more reverent. Not necessarily. There were priests who could do 'shotgun' Masses in Latin as well as they can nowadays in English. Just because it's in Latin, doesn't make it any more reverent.
I saw "shotgun" Tridentine Masses as a kid as an altar boy. However, they were done at 6:30 AM for the crowd going to work who had fasted the night before from midnight and who wanted to grab some donuts and coffee before taking the bus or trolley to work. No sermons on weekdays either. Futhermore, the noon Mass didn't exist. Nobody could fast for 12 hours and then go to Mass. So, you are right, but for what I saw as a valid reason.
Look, any priest can "hammer out" a fast Mass anytime. I have been to 16 minutes Masses on the way to work as recently as last month. I daresay Masses in al Anbar in Iraq for the Marines don't last more than 12 minutes or so.
