Currently, LoFi and LitePages use their own opt out logic which looks at past sessions and the current session to determine whether a user should be shown LoFi/LitePages.
This decision should be moved to the PreviewsBlackList and shared with other preview types (e.g. Offline Previews), so there is not a disparate experience for users who are shown different types of previews.
