You are making incorrect assumptions and running with them. As i stated in the article, and on this HN comment page, my issues were not with antiquated browsers. Safari on my iPhone 7 was failing to connect to sites other browsers were handling fine. I went down this rabbit hole of IP-based differentiation specifically because of that issue. There seems to be some sense that i published an article about the hardest way to achieve this. I promise had relying on SNI worked liked i expected it to, the IP-based section of the article would be absent. But it didn't and, like i said, IP's are cheap. Adding 1 step to a process of ubiquitous support seems like a reasonable approach to me.
