Orbitz might not care about the security issues raised by allowing
doubleclick to sign messages on behalf of their CEO and other

This is a security area spec, least privilege must apply wherever possible.
Sure, but don't forget that the D in DKIM stands for Domain. The
granularity is domains, not mailboxes. If you want per-mailbox
signatures, DKIM isn't what you're looking for.
