In an unrelated answer to an unrelated question one of our diamond mods stated that questions and answers about WP-CLI are off-topic. For example this one: wp-cli silently fails with error code 255
I originally come from Drupal StackExchange where questions about Drush (which WP-CLI is being inspired from a numerous times) are considered on-topic and have their own tag as well. On WPSE WP-CLI also has its own tag which makes me think that questions about WP-CLI must be on-topic.
But now I'm feeling insecure as a diamond mod told me WP-CLI is off-topic and I'm wondering how I should consider WP-CLI questions in the future? On-topic or off-topic?
