My opinion is that anything between /56 and /48 is fine. As far as I know, 
current RIPE policy gives the ISP the option to without motivation, ask 
for enough IPv6 addresses to offer each customer a /48 and I'd like to 
keep it that way.

But you're correct, it seems most deployments are going for /56 for no 
more reason than that it "should work for everybody". Of course /48 works 
as well as it's a superset of /56. I'm not going to give anyone who gives 
everybody a /48 a hard time and I don't want RIPE to do it either.
