Sending the serial number to the CA allows the CA to guess (with high
probability of being correct) that you are visiting the web page that
they sold the certificate for. This information can be resold to other
companies for marketing purposes (or other reasons). If there is any
money in this, I wouldn't expect Verisign to pass the opportunity up based
on other similar stuff they have done.
