I can see that Hetzner is starting with WORM capabilities [0]. I wonder if this nascent product is successful they'll consider some of the features that other providers offer such as mutating objects, storage policies, tiering, and conditional writes. I appreciate you've got to start somewhere and this looks terrific for an opening gambit. Kudos Hetzner.
[0] > Object Storage is mainly used to store and share data as it is not possible to edit any data that you uploaded to a Bucket (objects are immutable). So the main purpose of Object Storage is "WORM", which is short for, "Write once, read many [times]".
