Assuming all the subs reopen, mods will find out which parts of what Reddit has been saying have been lies or not, and will find out if they're actually able to mod properly.
My suspicion is that, like earlier when /u/spez was lying about the mods themselves, many of the mod tools won't actually work like way /u/spez claims. The subs might not be closed any more, but I wouldn't be surprised if they fill up with spam, AI-written ads, and troll posts.
