Happy friday everyone

I have a question about birth dates.
I just had a discussion with someone who suggested that new AAPs were required to have a birth day (year) in the 100 $a Surname, name, $d 2018-

For the creation of AAPs..

RDA states: Include a date of birth (see 9.3.2) and/or a date of death (see 9.3.3) if needed to distinguish one authorized access point from another. Record the year alone.

LC-PCC PS for presents an optional addition:

LC practice/PCC practice for Optional addition: Add a date of birth and/or date of death to new authority records, even if not needed to distinguish between access points.
I was taught by my trainer not to add qualifying information to AAPs unless needed - but that it is generally good practice to add 046s if that information is available.

This practice of adding birth dates to AAPs is optional, correct?
If it is not, why does the PS say it is for optional addition?

Also, If I did add a date to 046 $f ____-__-__ $2 edtf, am I also required to add that date to the heading? If so, where does it say it is required?

Are the NACO contributors out there e-mailing to acquire birth date for EVERY new access point being produced?

This seems excessive to me.

What do people think?

Thank you much
