Well, once more people learn about DLV (especially the NS override
extension that has been requested by zone operators), more and more
questions will pop up why we can't do this for NS records they don't
like for some reason. The genie is out of the bottle, I'm afraid.

The legal details for operating and using a lookaside zone are rather
interesting, which strongly suggests that this isn't a solution that
can be rolled out in a reasonable time frame. On the more technical
side, some very large operators have mostly out-sourced their DNS
operation, so they can't easily deploy an upgrade from ISC even if it
were available today.

I fear that many registrars make most of their money with trademark
violations of their customers. If that is indeed true, showing any
sign of responsibility could be suicidal.
