Since I belong to a parish that has four or five priests, and since many of them are reassigned somewhat frequently, I’ve been to confession with some 15 priests or so over the past couple of years.
Of all of them, two did not regularly ask for an act of contrition. But, after offering advice and assigning a penance, they do ask something like this — *and you’re sorry for all of your sins, right?
*
I think the key to keep in mind is that the act of contrition is meant, amongst other things, to demonstrate to the priest that you actually have contrition. If the priest is able to make this judgment without an act of contrition, then they may very well carry on and absolve you. One way or t’other, it’s Father’s call.
Having said that, I’m not sure what the actual Rite of Penance calls for, and whether or not this is a bit of an abuse. I suspect the question I mentioned above probably fulfills any obligation on the priest’s part.
