> {{FileSystem::OpenOutputStream}} silently truncates an existing file.
> It would be better to give more control to the user. Ideally, one could choose between several options: "always overwrite and fail if doesn't exist", "overwrite if exists, otherwise create", "creates if doesn't exist, otherwise fails".
> One should research whether e.g. S3 supports such control.
