Paul,

I would certainly be concerned about such a scenario, but I don't
understand how it's relevant to Peter's proposal.  Couldn't this already be
done today, by simply including such a hypothetical "parent opinion" record
in the glue?

For the scenario you're describing, the present lack of DNSSEC
authentication would not seem to be an obstacle.
