+1 on this proposal.

There is also a security consideration here as the birth year-month-day of 
a person is one of the key pieces of information necessary for identity 
theft.  Given how poorly most systems treat the security of 
vCard/address-book storage, I'd prefer to store the birth year offline and 
consider UIs that mandate a birth year to be broken.  The year is 
superfluous for the most common use of the BDAY field (birthday reminder).
