mind the "But think about it in the long term" part you quoted.

TODAY, real (non-geek) IPv6 customers don't know what they want or need.
And as long as they don't want anything bigger than a /48, you don't
have any more paperwork to do like for say a /56. So if you customer
insists on a /48, you have no real chance to deny that to him with a
valid reason. (Route-aggregation et.al. is no valid reason for a customer)
If you do so anyways, well, market rules apply and they just will go
somewhere else.
This is also true for renumbering cases - if you only give them a /56,
they probably won't even come to you as new provider.

But in general i see no problems with Default-assigning /56 as long as
you hand anyone a /48 if they explicitely request it.

==> "Think about it in the long term"

No need to change the policy. But this mailinglist isn't about policy
issues anyways.
