That it was historically "more difficult" to have more than one website per IP address particularly if it was using SSL because doing that needed amendments/extensions to DNS and other specs. We now have it, but still need to use a hack to cname an apex e.g set Google.com to bah-bahs-tenant100.s3.amazon.com. Adhering to the spec we need to set google.com to an ip address e.g 8.8.4.4
