>          Components: fs/s3
>    Affects Versions: 3.3.4

> In applications which do many single-file deletions on the same dir, a lot of time is wasted in {{maybeCreateFakeParentDirectory()}}.
> Proposed: add an option to disable the probe, for use by applications which are happy for parent dirs to sometimes disappear after a cleanup.
> file by file delete is still woefully inefficient because of the HEAD request on every file, but there's no need to amplify the damage.
