There's a lot more to effective program quality management than I can explain in a comment here. Forcing all developers to rotate through the maintenance team is one incentive not to ship crap because they might end up having to deal with it anyway. But more importantly you have to shift left the quality assurance and control activities to minimize the risk of defect leakage in the first place. And set up a closed-loop system where any leaked defect triggers a rigorous root-cause analysis that results in further process improvement.
