FYI, a motion was made at the 1/30/2026 AC meeting to advance this
policy to recommended draft. The motion was defeated 11 to 3 with 1
abstention. This means the proposal will continue as a draft policy
but will not advance at this time.

The meeting minutes will be published at
https://www.arin.net/about/welcome/ac/meetings/, I think within a
couple weeks though I'm not 100% sure. As primary shepherd, my
representations on the draft are characterized above, in prior
messages on this thread, and in the December meeting minutes.
