No, there has been no interest in this topic on-forum or off. I guess domains are sort of like the foundation of your house: If it hasn't fallen down, it must still be working...
For an organization or NP, the "owner" of the domain should be the organization, and a "role" email address used that can be forwarded to different people as staff changes. Then the Admin and Billing contacts can be the org, roles at the org, or for actual people, but in each case a different email should be used to insure that one or more people will always get any notifications that are sent. You can also enter in Tech contact information as well, but that may be used by the hosting company for the domain.
Using the organization as the own should insure that the domain ownership will be clear. If a staff member or (gasp!) a contractor or volunteer should be listed as the owner, future conflicts could cause the organization to lose the domain, which would be a bad thing, since the web site and emails could then be shut down.
