I don't think this should be done. create and update are two separate verbs in k8s and CRUD conventions more generically. We should not be re-inventing the wheel nor breaking existing conventions, which makes maintenance more difficult and UX more confusing.

Not to mention create --update is actually longer to type than update, so I do not see any benefit in this, only cons.

It sounds like you might be looking for apply, for example kubectl apply, which is a third, separate command

I believe that supporting version control for workflows and templates is crucial, rather than directly updating existing objects, which can be a risky operation.

The update action should still have many uses. If think the risk is high, can not use this API. Version control may be a more advanced use and requires more design.

Completely agree. In fact, we have implemented our own logic for updating workflows based on the Kubernetes client to enable intervention operations such as step skipping and parameter updates.

As I wrote above and elsewhere, I can agree to an apply command, but create --update seems like a confusing anti-pattern to me
