Yes, but it’s a very touchy subject. I personally find the prayers of the faithful in some places to be very, um, wordy, with a lot of emphasis on secular/political/environmental subjects, so ending with a nice gentle Hail Mary I’d find soothing.
And of course in the OF there are many places in Mass where the priest can choose one of (several) options. There are even still a couple of places (but only a couple, as opposed to prior to 2011 where there were several) where the priest can use “these or similar words”. I guess it isn’t surprising even 7-1/2 years after the change for some priests to still do things the ‘old way’ at times (like the ones who always say ‘for all’ instead of ‘for many’). It must be hard for them if they have had years or decades of being taught, or encouraged, to ‘make the liturgy your own, be open, be spontaneous’, to hear from some nobody in the pew, "But Father, I read in the GIRM’, especially in the cases either where the priest basically does everything he should, but gets ‘called on the carpet’ by officious ‘holier than the pope’ types who actually themselves are WRONG in trying to correct him! or else the cases where Father has been running his own personal ‘show’ for decades and is absolutely convinced (in the nicest possible way) that anything he does is divinely sanctioned and those who are trying to make him ‘conform’ to some ‘rubrics’ are just totally rigid, poor fools, and should be either assimilated or ignored. . .nicely, of course.
God bless our priests. God bless our lay men, women, and children.
