The "Contact Sales" plan mentioned in the Github discussion applies to the "Customer-Provided TLS Certificate Hosting Service" option, where the certificate is hosted on a shared domain map and where Fastly uses SNI to select the correct certificate to serve based on the domain name sent. Note that this option is only available if you meet their qualification criteria, whatever that includes. And it doesn't say anything about pricing, but there is no reason to assume that it's going to be for free. Also, that plan has been around for a while.
