I'm not sure, I'd expect it.  I'm not even sure it is a real concern, 
its just making me uncomfortable for some reason.  Maybe I just need to 
get over it and not worry about it.

But that wasn't explicitly clear, and I took it that it was intended to allow low end adjustments.  I'd like other to weigh in on if there should be a generic ability to reduce your IPv6 allocation.

As I see it this came up because we people asked to return all but a /36 
of their /32, they were initially told they had to return they /32 and 
the could get a new /36.  Business practice wise you fixed the immediate 
problem, I think.

After thinking about it for a while, if we even need any policy at all, 
we should just have a general policy describing how IPv6 block can be 
reduced by returning only part of a block, it should probably be very 
generic and apply to allocations and end user assignments.  It might 
even be better if it we a separate proposal all together.

What do others think?
