@yonzhan we've already moved all of these commands to the core CLI and would like to prevent future customers from installing the enterprise-edge extension. I'm assuming that we can do that by removing the source from this repo and removing enterprise-edge entry from the index.json. Is that correct?

@StrawnSC Yes, the source code can be removed directly. But if the az extension add -n enterprise-edge command is used in some users' scripts to install this extension, remove index.json may cause breaking change to them, so it is recommended to remove index.json during the breaking change window of CLI (Build Event and Ignite Event) For more details about CLI breaking change process, please refer to this doc breaking_changes.md

@zhoxing-ms are we good to merge + release this?
