It’s a minor point, really. Since the changes in the Fraction Rite (breaking of the bread, plus the Agnus Dei) I’ve seen priests continue to hold back from breaking some or even all the consecrated bread. Most guys seem to be still on auto-pilot, doing a minor elevation at “This is the Lamb of God …” and then breaking the large host afterward.
Sit in the purple chair and send off a memo to your priest. Should he complete the fractioning during the Agnus Dei? Should you evenbother to tell him, or just let it go?
