Someone pointed out to me in private mail that the /48, /64, /128  
text in ARIN's policies revolves around recommendations, and  
responsibility for assignments to end users rests ultimately with the  
ISP/LIR/call-it-what-you-will.

I think it's fair to say that most people who assign v6 addresses to  
customers follow those recommendations, but I don't have any science  
to back up that assertion.
