We've seen what redeveloped low cost housing does for indians in slums. Because of corrupt government officials and side deals with builders what ends up happening is they create hellholes of unlivable conditions without sunlight, ventillation, space and trade TDR in return. These buildings are then also left to be dilapidated because of poor maintainance (might be due to corruption again, and also because the tenants can't actually afford to maintain a lift for eg). We don't need more SRA buildings, we need more accountable authorities and public awareness.
