I would be happy with the simpler solution that any AfD without explanation could itself be speedied on sight.
I suspect an unexplained AfD nomination isn't a big deal by itself, since practically every nomination gets a few votes and those votes will probably be what decides it. I'm more concerned with the votes themselves; a string of "delete, nn" or "keep, notable" can swing the outcome of a vote but provides no actual basis for it ("me too" votes provide a basis by proxy, but don't themselves add anything new to the discussion). Deleting individual votes is likely to be pretty contentious but maybe if there was an obvious policy against considering them when closing the AfD there might be fewer such votes cast in the first place.
I notice that [[Wikipedia:Deletion_policy#Commenting_on_a_listing_for_deletion]] already sort of implies this, but perhaps it needs to be made more explicit.
