Google's CardDAV server isn't standards compliant ...
Maybe I've misunderstood something, but if gmail didn't do this, what's to stop me from sending emails that look like they come from your address?

Nothing. The standard allows you to put anything you want in the From: header. Sometimes I send emails from Santa Claus or God. The envelope information is still there.

Actually, not "nothing." If the MSA doesn't like this, it is free to reject the email. But not to change its content.
