The kicker is that (from what I can tell) there's much less wiggle room for late submissions, so we'd all have to be on our A-game and committed to being on time for this to work.
I'm pretty sure extensions can still be given and the mod can delay reveals with the AO3 exchanges - plus from what I've read on a multifandom exchange meme (which is a good place to ask questions about running exchanges if you have any - just pm me and I can give you a link if you like) a lot of people post what's called a bus-test fic (ie if you get hit by a bus after posting it still passes as an acceptable story) and then use the week or so between due date and reveals to tweak their fic, or add extra words to get it to best possible fic.
