Purely speculation, but I would imagine that Sunday morning mass, as the ‘big gig’ for the parish, means that, as more people are in church, more people want to see the priest for something (blessing a rosary, mass intentions, etc). If he was closeted away in the confessional none of these people would be able to see the priest.
That said, it would be possible for Sunday mornings in a Parish with more than one priest, but there are not many of those about; or I imagine people would get used to not being able to see the priest before mass and wait until after (although this would have complications as priests will usually say goodbye to the congregation as they leave, increasing the wait, and there may be baptisms after mass).
I imagine any priest will hear a persons confession before mass if you were to tell the priest that you had a mortal sin to confess, in order to allow you to fully take part in the mass. Scheduled confessions tend to be frequented (in my experience) by those who confess regularly because they choose to (and there’s nothing wrong with that) rather than by those who need to because of mortal sin.

P.S. Perculiarly, our parish has Saturday confessions straight after mass (10.30am), during a period of exposition of the Blessed Sacrament.
The difference between having to wait to have a Rosary blessed and not having access to confession prior to mass or access to confession, period, could literally be heaven and hell. Confession after Mass deprives people of receiving the Blessed Sacrament, or worse yet, leads to the reception of the Body of Christ in mortal sin, and we all know what St. Paul said about that…
The reason that I bolded confessionals is because these days one is lucky if their Church even has confessionals. IMHO there has been less and less focus on the Mass as a sacrifice, the reality of hell and good and objective reality of good and evil. This reduces the focus on what the sacrifice was and is for - a meritorious action for the remission of sins.
Side story - Today I missed the EF and went to the OF to fulfill my Sunday obligation to God. The Gospel reading was John 6: 51-58:
“I am the living bread that came down from heaven; whoever eats this bread will live forever; and the bread that I will give is my flesh for the life of the world.”
This, one would think, would be a great opportunity to expound upon the true meaning and significance of the Blessed Sacrament - the greatest gift given to us this side of heaven. As I recall, the Priest did not talk even once about the consecration that takes place on the altar as being a sacrifice. I listened for that word. There was brief mention of Jesus sacrifice on the Cross, but he didn’t carry it through to the
Sacrifice of the Mass. At least he did a decent job of driving home the real presence, though without a sufficient understanding of the Mass as a sacrifice, a true appreciation for the Real Presence is difficult. Somehow the homiy morphed into a longer talk about how much Scripture focuses on and promotes song and how essential it is for everybody to sing the hymns, and loudly and boldly at that. :shrug - Not too sure how the two ideas had much correlation to one another, but such is life. Anyways, I digress…
Thus, there is a prevailing lack of awareness of sin or what constitutes a mortal sin. I know many people who think that confession is only for the likes of a murderer. All of their sins they consider to be of a “minor” nature and assert that they can confess straight to God. I’m considered a strange duck in my family when I say I’m going to confession. Penance is a Sacrament we need more of and simply cannot go without. I’ve heard it said - “Once one falls into mortal sins, the lights go out and they can no longer see things for what they really are.” I like that quote.
