I recently registered a new EU domain name. I noticed that its detailed whois data on EURid site has different fields than my "old" EU domain.

Namely, the old domain has a section called "Registrar technical contacts", whereas the new one has "Registrant technical contacts". At my first glance (before actually reading section headings ) I thought the new registration just didn't implement the registrar's privacy/proxy features, and only after checking the headings I noticed this "slight" difference.

What's the reason for this? Some new policy that only applies to newly registered domains perhaps?
