RFC 6177 clarifies the /48 recommendation.  The Fine Manuals won't 
really explain why it has been argued that residential users should 
be given a /56.

Justification is appropriate if you are dealing with a scare 
resource.  There is a management overhead in dealing with that.  It 
is easier to hand out ample address space so that people can do what 
they want without having to come back to you for additional address 
space.  A /48 keeps it simple.
