I don't use instant booking anymore, but when I did, my pre-booking message more or less thanked guests for choosing my listing, asked them to tell me a bit about themselves, e.g. the reason for their trip and who they are travelling with and to confirm that they had read the full version of the house rules, paying particular attention to X, Y, Z (in my case, the cats and smoking policy and then whatever point was most relevant to that particular room, such as the stairs, any traffic noise etc).
However, it's important to mention that not all guests who IB respond to this message. Another host, I think it was Emilia43, discovered that guests who sent an enquiry first and then IBed from there, never saw the pre-booking question. This is obviously a glitch that needs to be fixed. All guests who IB should be presented with the pre-booking message when they book, because that is what is promised to hosts.
Also, I'm glad that the pre-booking message was reinstated. However, far more problematic in my opinion, is that hosts can no longer require guests to have verified government ID. I know that Airbnb will argue that it is now requiring all guests to be verified, but if you read the details of that verification policy, nowhere does it state that guests will be required to submit government ID. It says that hosts might ask for it if their building or local regulations require it. I am afraid that is not good enough, and therefore Airbnb needs to reinstate the filter allowing hosts to choose verified government ID.
Plus, we are still waiting on answers as to what the 'good track record' actually means. I know I can be a bit of a cynic, but I find it suspect that the wording around this is so incredibly vague and that hosts and the moderators still don't know the answers nearly two months on...
