As always, your experience may vary, but it seems like many operators are 
starting to settle on /48 as the cutoff point.  This seems reasonable to 
me, since some of the RIRs are also settling on /48 as the smallest 
prefix they will allocate.  That said, there are some people who don't 
filter (much), so it's not unusual to see smaller prefixes show up in the 
global v6 view.
