Because we have released v11 so as we respect the permissions set on the source instead from which the backup is taken for all the folder's content. If we begin to enforce it we may break some cases. If a new option is introduced, it seems to me that the default should remain what has been released with v11, but that it is additionally possible to enforce group permissions or non-group permissions at will on the backup taken for all the contents in the data folder, including the root folder, created manually or not before running the pg_basebackup command. -- Michael
