No. It's not hard. You just need to reverse the order of
operations. Remove the DLV / DS then once they have cleared
the caches you can convert the zone to unsigned.
If you have announced trust-anchors then it becomes harder
as you need to find and remove those trust anchors.
This is where signing the root / using dlv becomes so
important as there is only a single trust anchor to manage.
You don't end up with millions of people each with a copy
of your trust anchor.
