The idea is to provide a more “harmonious“ quarantine environment for arrivals, so that they can roam in a more spacious area. that would unlikely shorten quarantine. syncd well with a zero tolerance policy, I'd image a decision was made that to live with covid borders will be made more welcoming but the quarantine will remain in place for a long time. should also serve returning outbound travelers, though only few could afford going on leisure trips with many days in quarantine.
