And what possible problems are you expecting with leaving zone "com" { type delegation-only; }; zone "net" { type delegation-only; }; in the configuration?
They should be delegation-only in any case, shouldn't they?
that was the basis of the enhanced version of the feature, which is spelled "root-delegation-only". non-delegation data in root or toplevel domains is possibly useful (like www.$TLD) but not necessary (an NS can be put in to achieve the same effect with an extra "hop".)
well, thats up to the zone admin. :) my concern is mostly along the lines of folks who will do things like:
zone "waw.pl" { type delegation-only; };
to random zones that they think -SHOULD- be delegation-only, regardless of what the zone admin specifies.
