Besides the automatic app sleeping, we sometimes want to manually force instances or whole enviroments to sleep / pause / stop without removing it. So you will not lose all config.

Use-case: using staging environments for projects. Depending on the project, ongoing development on a specific project can be idle for a while. For that period of time you want to shutdown or pause the staging environment (or all instances in it) without losing all configuration. Whenever the development on a project picks up and you need a staging environment again, you want to reactivate it easily.
