It might be beneficial while not being optimal on its own.

The obvious example is if it has different behaviour around local minima, it could be an altenate pathway out.

I have often wondered if doing training with radically different aproaches for the first few iterarions would avoid any method specific artifacts before the weights had time to denoise.
