I would agree with that in the couple weeks we started using postscreen on some larger domains. However, we do still greylist, but, only for certain cases. Mailfromd provides the logic to allow us to very selectively greylist. So, maybe 2% of real mail ever gets greylisted. So, 98% of it is fast. The 2% is usually strange cases, mis-configured, etc.
