>          Components: fs/s3

> When you create a file with overwrite=true, you don't care that a path resolves to a file, only that there isn't a directory at the destination.
> S3A can use this, bypass the {{GET path}} and only do a {{GET path + "/"}} and LIST path. That way: one HTTPS request saved, and no negative caching of the path to confuse followup checks.
> That is: better performance and consistency
