So, Michael, for clarity are you in support or opposed to this proposal?

In addition, by allowing IPv6 space to transfer in this manner, the
careful and sparse allocation methods ARIN and the other RIRs have been
doing in order to maximize some semblance of aggregation will become
less effective. A good chunk of the fragmentation in IPv4 space is due
to address blocks that have been acquired over the course of time
(sometimes through M&A) that are no longer aggregable. Keeping ARIN in
control of IPv6 space can help ensure (or at least it won't undermine)
the goal of having a minimum number of aggregable IPv6 prefixes
announced per ASN. We know that transfer policies will increase
fragmentation in IPv4 but we think they're a necessary evil. They're
not a necessary evil in IPv6.
