In ArcGIS Enterprise you may license the server multiple ways, to include over the internet, by providing an ECP directly, building a 'secure' request via a form (and submitting/receiving the license file from different machine out side the firewall), or using my.esri.com to generate directly generate the provisioning file. Issue is once you have licensed a server there is currently no way to RETURN a license. This could easily be required if you had a failover license, developer license, staging license, and production license for the same product and later you wanted to rearchitect your environment. Similar to the old ArcGIS Administrator, we need a Deauthorize button in the authorization wizard that will Return the license so it re-appears in my.esri.com.
