It's not a must have if you manage your own network. There are always 
other options. That being said, if you are an ISP handing out prefixes 
to customers, there is an expectation that the customer will probably 
use it given the direction CPE implementations are going. Thus you have 
to predict that if you don't want to setup all your customer's networks 
for them, they'll probably be using /64 per subnet.
