Because of the Google Drive StorageFile now contains yet another field, `id`. For other storages `id` == `path`, and thus all common Requests (such as SavesSyncRequest, DownloadFolderRequest, etc) must be using id() instead of path(). That way these Requests won't cause id resolving which could be quite slow (when you call it for all files in the folder, for example).
