Happy early [long for some] weekend!

When adding a variant access point to an existing authority record [updating a NAR to RDA and have encountered a variant name for a person, and note that there's no conflict ]

Instructions for VAPs at 9.19.2.1 state:

"Include additional elements if considered important for identification. Apply the instructions at 9.19.1.2–9.19.1.8, as applicable."

Which of course leads me to 9.19.1.3 and its LC-PCC-PS which states 

"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." [emph mine]

Thus am I to conclude that because this is not a new authority record, but a new access point in an existing authority record. I am free to not add the date to the VAP? [I will be adding date as per my cat judge of the optional addition] I'm just curious if my reading is correct.

thanks!
