I found it confusing that the draft talked about upgrading A / AAAA credibility 
in
two places, but then I convinced myself that section 4 was about addresses 
learned
from authoritative NS RR data, while the paragraph in the middle of section 3 
was
about addresses learned from non-authoritative NS RR data.  

It would be good to clarify and/or combine these IMO. Especially because it 
should
be the common case that the two NS RRsets are (mostly) the same and the resolver
would only need to revalidate the addresses once, not twice.
