<div>If it is to declare a protocol as historic because it is not longer used enough and we should not do more work, then I think is not time yet.</div>

</div>
<div>If it is to make awareness that we need to deploy more IPv6 and stop using IPv4, the impact would be minimal compared to the complications that it would create.</div>

<div>As discussed in other places (sunset, the session, etc.) I would found more value in a document setting the path to make IPv4 historic.</div>
