IMHO authors of the paper highlight a valid point:

There is no _explicit_ guidance for consumers of DNS data which explains that results of DNS resolution process must be treated very carefully.
It is clear to this group of DNS experts, but I think we should lend a helping hand to DNS consumers and at least explain why consumers have to check everything.

Is anyone interesting in writing a short RFC on this topic?

I think this could be summed up as "Validate any input provided by sources you don't trust" with a subsection "don't automatically trust DNS data".
