Also good question and something we've thought about. The difficulty there is actually getting the forklift tines out after placement. Actual forklifts in real warehouses rely on pallets as an affordance for manipulation, and we don't have that luxury here.

There have been some neat attempts with short conveyor belts as end effector tools [1]! Generally these systems rely on being able to rearchitect a significant amount of the process (building a controllable conveyor belt or rearchitecting part of the bag-room), and we're focused on dropping into existing processes.
