Drupal Render cache should be an option for drupal site:mode dev. We want make sure that DrupalConsole align with Drupal best practices and this seem to be part of the debugging documentation.
drupal site:mode dev
For more information about the implementation please visit - https://www.drupal.org/node/1903374#drupal-render-cache
Whenever this is been implemented we need to remove the disclaimer of that this is not been implemented in Drupal Console at https://www.drupal.org/node/1903374.
We should add to the services.yml file in site:mode dev
i did a PR for this at #2998
