Sure, you're right in most cases. In the use-case I had, it's a private registry with "immutable" tags (at least enough to stop accidental overwrites - and it is a homelab, so if someone else did it, I'd have worse problems ;))

The point was more about using null_triggers (or `terraform_data` I see) and using the trigger replacement, with the docker resources as purely an illustration.
