Regarding the Vatican suppression of private Masses: As an undergraduate resident at Villanova University in Pennsylvania, I attended many Masses celebrated by individual priests in the local chapel, at one or another of the side altars. 

For me, it was very edifying to know I could go to the chapel in the early morning, and attend Mass before many minutes passed. As far as I know, the priests were unaware of people like me in attendance, but the practice helped to cement the faith I remain graced with 60 odd years later.
