TNT duping should get a good replacement

TNT duping has mixed opinions, some people use it a lot and others hate it.
A good start to replacing TNT dupers would be renewable sand for the TNT.

But then things like cobblestone generators need to be refilled manually so maybe also introducing autocrafting in a not to powerfull way like the mod QuickCarpet from DeadlyMC does would fix that issue an open a wide variety of options in redstone farms.
