The Rif and the Rosh are used as two poskim from three (Rambam) by the Mechaber to determine halacha. They don’t bring what is called הלכתא למשיחה halachas which currently don’t apply but will apply at the time of Meshiach. So the Kollelim have to concentrate on producing poskim and emphasizing the halachas derived from the learning. Even though there is a mitzva to learn, it is not the responsibility of individuals to support learning where halacha is secondary. The emphases should be מבין דבר מתוך דבר understanding one thing from another.
