Alas, the history says that way too many of the PhDs did not.  There
are lots of astronomers who wrote down their concept of origin and
meaning of the new second but turned out not to understand what the
new value of the second actually represented.  Sadler is nearly alone on
record expressing the opinion that the leap second was a bad idea,
everybody else thought it was the perfect solution.

So it is important that documents which make a change include
detailed discussions of best understandings of implications.
But that has never been the case, and the documents being submitted to
WP7A this week continue the tradition of not explaining the whole story.
