@Fred13, while I don't think they will offer the Super Strict 30 & 60 to very many people, I think certainly you will keep it, and I think AirBnB will keep it.
Someone else posted an article written for people in the Vacation Rental industry (or VR, as they call it), and those industry people demanded something essentially like Super Strict 30 & 60 for their resort-style properties. The article outlined 14 or so demands they had of AirBnB, and how AirBnB was changing their policies to help the VR industry people. (Not day-to-day hosts).
Anyway, AirBnB might keep Super Strict 30 & 60 very close to the vest, but some VR people with a lot of listings really want it to continue to exist.
