Could you please address the fact that just about everybody uses base backups + later WAL to have a short data loss window? Integrating the WAL files necessary to make the base backup consistent doesn't achieve much if we can't verify the WAL files afterwards. And fairly obviously pg_basebackup can't do much about WAL created after its invocation. Given that we need something separate to address that "verification hole", I don't see why it's useful to have a special case solution (or rather multiple ones, for stream and fetch) inside pg_basebackup.
