They can help by having the hardware show some of the cases where the software is doing the wrong thing, but a reliable system will require a solution which works on an R5000 or R4600, where there is no hardware detection. That is, in most cases where an R4000SC would give you a VCE, an R5000 will give you corrupted data (in general, not every time). The solution needs to be correct by construction, not by testing.
