Despite a number of objections, consensus seems to be
forming on WP:V
to include the line "If no reliable, third-party sources can be found
for an article topic, Wikipedia should not have an article on it." in
the policy. This line may be familiar in its more-cited form, "A topic
is presumed to be notable if it has received significant coverage in
reliable sources that are independent of the subject," from WP:N.
It's notable (no pun intended, not that anyone will believe me) that
the former does not include the word "significant" while the latter
does. That would make WP:V require a weaker form of notability than
WP:N. It's not a simple case of WP:N being included into WP:V.
