The greylisting insert delay in delevery and sometimes the email have to be delever fast.
For example: on some public wireless network, you have to register to have access to the internet. You can access internet without authentification for 15 minutes. In this 15 minutes, you have to register in the captive portal and then go confirm your inscription by clicking in a link received by email. If the greylisting insert more then 15 minutes of delay...
I think technologies like SPF have a better futur.

Use greylisting: if they're bots, they will not even reach your SA.
Greylisting is a force.
Use the Force!
