How Team Foundation Server saves you from a potential mess with IIS and SSL

This is an example of how TFS is robust enough to prevent you doing silly and potentially costly (in terms of time) mistakes.
Let’s say you are configuring a new instance, and you just got your SSL certificate installed on the machine. So you select the HTTPS and HTTP option in the configuration settings, and you select your certificate. And you get an error:

Clicking on that link creates the correct bindings for that certificate. Fair enough.
But the Public URL is not what you like, so you change it to something else. And you go ahead. The result?

The readiness checks prevent you from doing this. It also checks for SNI validity amongst the other things, something that comes handy when you deal with Chrome.
