Ending Support for Expiration Notification Emails

Providing expiration notification emails means that we have to retain millions of email addresses connected to issuance records. As an organization that values privacy, removing this requirement is important to us.

I fully support the privacy argument (I didn't realize it has been mandatory to give some emai address to get a cert) but why not make it optional instead?

The reminder email from them has saved me once when originally "temporary" domain was not so temporary after all and I forgot to set up auto-renewal and monitoring for it.
