It is more wrong than useless: From RFC 4035:

All DS RRsets in a zone MUST be signed, and DS

RRsets MUST NOT appear at a zone's apex.

<p>I've also encountered DS in the middle of a zone -- i.e. on a
name without NS, in this case also with some child names existing
within the same zone.</p>
<p>I didn't find that it's really forbidden, but on the other hand
I've had no motivation to fix Knot Resolver's
forwarding+validation mode to tunnel through such an obstacle.
That zone got fixed eventually, too.<br>
