I doubt this will ever show up as a real filter, though. Maybe a "this is this host's only listing" badge or something could happen.
To you.
AirBnB hosts tend to be open and gregarious in my experience. The hosts who are not (e.g. just need the money) you just change your behaviour to suit (or avoid due to signals in their listing).
As a guest, if I don't want to interact with the host, I get a hotel instead.
I've even had some hosts say help yourself to what's in the fridge. I usually don't, as that still feels a little weird to me, but generally it's really interesting to get to see how someone else that you don't really know lives.
