It`s not about* lack of homages. It`s about the way they are being presented. In P2 those were served with witt, that`s why they don`t hurt as much as Brody dowsed in mud saying "comon kill me!..."
Another poin it that P2 had allot of their own classic quotes ("Shitt Happens"), of which Ps was lacking .
