Private space turn public information .
Already, private space for records that have been set private (such as persons born in some countries) even though they are deceased allows the record to automatically turn public 150 years after the birth/death of that individual.
Could a similar thing be done for others in private space who are in that space as "living" after 150 years from their birth date? This way, that information is not lost, privacy is preserved, and when a FamilySearch user passes their private space work will eventually be brought out to the light.
For instance, I have the information on my living friends in my private space. Things like their college, life sketch with service records, their residences as we grew up. When I pass, if I am the first of my living friends, this information will never emerge from my private space. They are not interested in genealogy so would have no interest in taking over these records. But if there were a 150 year default from their birth year (which is in my private space records) then it would one day emerge for general use.
