The paper is not suggesting that date codes be eliminated; only that
restrictions not be put on components with respect to date codes. For
example, many companies have policies stating if the date code indicates
components are more than a year old, the component must be rejected. The
white paper suggests that because of the advances in manufacturing and
storing the components, they don't "get old" anymore,  and that the date
code doesn't really indicate the age of the component anyway (since the
coding is not standardized). For these reasons, it is suggested that date
code restrictions should not be placed on components.

I don't believe the paper is implying that traceability could also be
eliminated.
(If it is, they're nuts).

I wonder how long it would take the component manufacturers to start
marking
date codes again if a problem was found within a part and they either had
to
test everything they had to sort out the problem and throw everything away
and start over? I agree that having the suppliers sort for date codes
because of assumed solderability problems is a problem but there really
needs to be a date code.
