- * What core needs from the Remote Desktop plugin, resolved through the plugin
- * registry rather than an import: restarting its guacd WebSocket server after
- * an admin edits the guacd URL setting.
- *
- * The plugin publishes "remote-desktop.sessions" through ctx.registry on
- * activate and the registry revokes it on deactivate. A restart while it is
- * off does nothing, because resurrecting a server the plugin does not own
- * would be worse than doing nothing.
