Thanks, Matt
This is precisely the subject on which I hoped to get community feedback.

How I subdivide and allocate addresses
internally and downstream is not a matter
for the community to vote on; that's between
me and my customers.

Draft Policy ARIN-2015-10
Minimum IPv6 Assignments
Date: 23 September 2015
Problem Statement:
ISPs may believe that they have an incentive to obtain smaller blocks than
they really need, and once they receive their allocation may subsequently
issue blocks smaller than their customers may need in the future. This
policy seeks to encourage the correct behavior by reiterating the smallest
reasonable sub-allocation size and by discounting any space which has been
subdivided more finely from any future utilization analysis.
Policy statement:
Modify section 2.15 from "When applied to IPv6 policies, the term "provider
assignment unit" shall mean the prefix of the smallest block a given ISP
assigns to end sites (recommended /48)." to "When applied to IPv6 policies,
the term "provider assignment unit" shall mean the prefix of the smallest
block a given ISP assigns to end sites. A /48 is recommended as this
smallest block size. In no case shall a provider assignment unit for the
purpose of this policy be smaller than /56."
Modify section 2.16.1 from "A provider assignment unit shall be considered
fully utilized when it is assigned to an end-site" to "A provider assignment
unit shall be considered fully utilized when it is assigned in full (or as
part of a larger aggregate) to a single end-site. If a provider assignment
unit (which shall be no smaller than /56) is split and assigned to multiple
end-sites that entire provider assignment unit shall be considered NOT
utilized."
Comments:
Timetable for implementation: IMMEDIATE
