As many have mentioned this is not a new technique. It has been in use for racing engines (and probably very high end performance engines like Ferrari or Lamborghini). I am not sure when GM started using this process for Corvette engines but the LS7 for sure had it, anyone know if the LT5 was deck plate honed? It wouldn't surprise me either way. I think the big news here is that unless Ford has used the process on high end mustangs, this is likely the lowest price point car that has ever been offered with this process from the factory.

I would also assume that this process has been somewhat automated for LSA production.
