We will implement this when we add allow_container_deletion #38999, right?
(Or we may add one more option only for this something like allow_all_containers_deletion?)

Personally I think it's reasonable to never implement this.

s3fs doesn't infer that it's OK to delete all the buckets from these options and doesn't have an option allowing deleting everything. I think anyone that wants to delete all containers will either do it manually or via the official SDK if the want to do it programmatically.
