It would be great if K2 allows the deployment but not to activate right away. Similar idea as Salesforce where you can move changes to one environment to another but also allows you to when to activate that change. Also K2 should allow inter connect on environment as automated deployment instead of using Package and Deployment. You can schedule you change ahead of time and validate in advance. Then K2 can save the configuration and feature/setting you have selected on scheduled deployment time and auto deploy the change.
