Some time ago I proposed that policy [1] at Meta and announced at foundation-l. I was thinking that foundaiton-l announcing is enough.
This morning (in my time zone) we had discussion with one en.wp admin who really doesn't like this idea. There is six days more for discussion (before voting), but it seems that Wikimedians from en.wp are not introduced well in this issue; which means that it is possible that we will need more time for discussion.
So, please, go to mentioned page at meta and its talk page and discuss. Some Wikipedians started talk about en.wp local policy which is in relation with global permissions [2]. So, you should go there and discuss, too.
The main issue regarding AVFs is that they would have rights technically (like stewards have), but they would not be allowed to use them if it is not according to the local policy. Every AVF who doesn't follow those rules would lose their rights immediately. And you are making your local policy. Please read both policy proposals carefully.
(Email is CC'd to foundaiton-l for keeping people there up to date.)
