Re: [sig-policy] New Version: prop-101-v003: Removing multihoming requir
I agree with point (d) and I would support with a proposal which contained it.
I disagree with point (e) as it stands and I would not support with
any policy which contained a similar clause.
I believe that placing a sunset clause on this policy sets a bad
precedent. As mentioned by the APNIC secretariat, there has been no
example of this being done on any previous proposal.
As mentioned by David during the meeting, there is nothing to stop any
other proposal being raised which would repeal prop-101 if a situation
arose.
As such I do not support version 003 of prop-101.

Dean
