Imho whois private data should have one mandatory field: holder/owner. It details who controls the domain, be it a individual, an association, a company, and so on. There is no need for phone numbers of emails there (unless the controller wants to add that). This is how it works with .fi domains and I find it perfect. You can still get enough data that should you really wish you can contact the owner but you can't really automize it.
