We are seeing about 6,600 046's in our VIAF data, all in the LC/NACO file.
Since we are not yet picking up the 046 information for VIAF, we looked a little closer at how they compare to the dates in the headings themselves. The 046 often has more information (e.g. month and day) in it. In about 40 records the 046 date appears to disagree with the heading (or in some cases what we are picking out of a 670), not supplement it. We'll submit those for review.

Not at all. The rules have been in place for a long time.
AACR2 22.17A says:
"Optionally, add date(s) to any personal name, even if there is no
need to distinguish between headings."
The LCRI says:
"Apply the optional provision. This means adding a date whenever it is known."
For LC/NACO participants, this applies when establishing a heading in
an authority record for the first time. There are additional
instructions on when it is permissible to add dates to
already-established headings.
I realize this is getting away from the dates as "information" in 046
vs. dates as "identification" in 100$d aspect of the discussion, but
it is worth getting straight.
