Good to know. At one time a free cert provider (now defunct and has been
dropped from all major browsers) would certainly not sign a cert with
more than one SAN for sure.

I suppose if I were big brother and were trying to track down illicit
internet use I probably would look at the cert and see if the SANs
listed any suspicious hostnames like vpn!
