Objects in a swift container can be deleted by either explicitly deleting them or by setting a expiry timestamp on them. Is there a performance difference between the two? For example, when I want to delete an object, instead of deleting it, can I simply set the X-Delete-After attribute of that object to 0? Is one faster than the other? </div>

Delete will require creation of a new version of the object, truncating it to a 0 byte file and renaming it to change the extension to ".ts". Seems like less work is done when object expiration is set.</div>
