Is CdnUrl still supported?

[Nashuim]

The option for CdnUrl seems to not do anything when set:

"webOptimizer": { 
  "enableTagHelperBundling": true,
  "cdnUrl": "http://my-cdn.com"
}

I also can't seem to can't seem to find the CdnUrl option being used in the Core code. Is there an extra nuget that we need to get this working?

I'm also interested in this, if anyone has more information please let us know.
