Don't mind the birthday (have been ID'd once or twice in both F and Y in the past and wouldn't mind avoiding that) and it is a nice customer service touch (though it would be better if they actually did something with it like offer a complimentary drink if in Y).
What concerns me are the addresses and any potential information about how the passenger arrived in that seat (upgrade, award ticket, etc.). Ticket specific information opens up the possibility of biased service for example a flight attendant who doesn't like upgraders serving them last or not giving them full attention (when IMO FAs should be ticket agnostic and any bias should be by status to reward loyalty and that's it).
