Why do I have a binding for SitecoreApplicationCenter in my web.config?

I was doing some cleanup in our config files, and I noticed we have a binding called "SitecoreApplicationCenter".  Looking through our Sitecore solution, I didn't see this referred to anywhere, until I opened the Sitecore.Kernel.dll.

This reference is used when communicating with Sitecore's App Center... just like it's named.  It will be used when making calls to the service: https://apps.sitecore.net/appsservice.asmx

We'll never use this on our frontend servers, so I transformed it out of that config.  But I kept it in our Content Manager server config.
