Can’t say I noticed it much after I became an adult, but I don’t think I ever went to a Mass that didn’t include a wedding as an adult & a portion of the congregation at a wedding wouldn’t be Catholic. Funerals include or are a Mass, right? Still, a portion of the congregation wouldn’t be Catholic. Like I said, I got the impression that the curtsy & holy water went the way of the doily on the head.
They may have gone away but they’re back now, at least in every Catholic church I’ve been in. Parishioners also demanded the return of the Stations of the Cross, and kneelers in most cases.
