As one of the authors of the text being discussed, I can confirm that
the intent for the "SHOULD NOT use deprecated address as source" was
for "active opens" only, not on (say) passive opens.

The introduction shouldn't/needn't be the definitive text. But if we
can make it more clear, we should.

How about changing:

    (e.g.,the opening of a new TCP connection)

to

    (e.g., an active open of a new TCP connection)

I'm assuming that "active open" vs. "passive open" terminology is
well-understood (I think it's in RFC 1122).
