The problem comes when you just want to connect your laptop to the 
cluster and you have no idea about what node numbers are being used.  
You want also that your machines already started join the cluster.

Your way surely works but what about machines that select a unique node id 
automagically? If we want something like that the best moment to begin 
developing it is now, later it will be much harder make a more flexible 
aproximation than a boot option.
