Could you elaborate? I am not aware of a DDoS mitigation technique
which is disabled by mandatory technical tests before delegation.

Same question.

Are you sure you don't mix registration with delegation? I see the
point of registering without delegating, I completely fail to see why
delegating to or could be useful.

Tests done with our DNSdelve tool <http://www.dnsdelve.net/> show
that, one year after registration, more than 90 % of the .FR domains
still pass the technical tests.

Disclaimers: .FR require successful technical tests before delegation
takes place. They are done with the Zonecheck tool
<http://www.zonecheck.fr/>. registration != delegation. We have not
one domain with 8.8.*.* as a name server. The tests are obviously done
by the registry, not by the registrars.
