I'm not understanding what you mean with 'single command'
here. Currently there's no way to do this safely without configuring a
high enough wal_keep_segments.
You can (since yesterday) manually create a slot, run pg_basebackup, and
drop the slot. But that's not safe if your script is interrupted
somehow. Since many base backups are run in a non-interactive fashion
asking for intervention to clean up in that case imo is not an
acceptable answer.

Or the connection dies/is killed, or the server is restarted, or ...
