It seems unlikely that they'll have to make it work for thousands of subs, and quite frankly if they do then they'll likely have a new cooperative group of powermods that they can delegate most of the work to. I think the real thing that Reddit has to worry about is that upset activists could directly start spamming the site in order to justify their warnings about what will happen without mods. "Nice subreddits you have here, would hate to see anything happen to them if you don't accede to our demands."
