Ah, okay. I hadn't seen that there was a longer video. Will have a look at it when I get a chance.
From what I understood, there was already a tick box about following rules that guests had to check to confirm the booking (but to actually read those rules there, the guest had to click a link).
Airbnb have been promoting that, along with other reassurances, as a reason hosts don't need to be scared to use IB. I am pretty sure that, when I turned off IB, the messages that popped up trying to convince me not to, include a point about guests having to agree to house rules when they book. So, that part is nothing new.
What I understood, from the video that I did watch, was the new bit was being able to select from a menu of 'ground rules' (house rules basically) to highlight for guests to agree to. If that will now show in the booking process, then that's some progress at least, but if it only shows on the listing then, again, it's nothing new.
