I am thinking "no." DKIM's ability to identify a domain owner is not
limited by registration authority rules because there may be or will
be reputation services separate from the registration authority.
Besides, I don't think DKIM is ever identifying the owner of a domain
name since that information is not in DNS. If the Acme Widget
company has the domains acmewidgets.com, acme-widgets.com, and acme-
widgets-inc.com, there is nothing in DNS that tells me all three are
owned by Acme Widgets (well, nothing you can rely upon).
