From a straight mechanical connection perspective: In this case, where there is a cantilevered bridge, creating a torsion stress on the foot to begin with. Glued or not, the curved shape of the foot would result in reducing the available connection to the soundboard panel at least in half. This bridge will want to rotate under load. The load will be pulling up at only the screw locations, pivoting at the back edge of the foot. If glued, the upward restraint is spread evenly across the entire span of the front of the foot. In order to pivot, the glued foot needs to bring the soundboard panel with it (which under serious load it probably will). From a mechanical standpoint the screw only connection seems a bit optimistic, unless downbearing is kept near zero.
