For once we agree. NSI should have stopped this practice long ago. You'll
be pleased to hear that there are other name registries (for instance the
one serving the "no" (Norway) TLD that actually perform this check.

Note that checking when an application is received isn't really enough.
In Norway we run regular (monthly) checks of all the second-level domains
under "no", and we always find a number of name servers which have ceased
being authoritative in the time since last check.
