No, because they only perpetuate an existing conflation of concepts.

"node name" as you have described it is simply the "certificate name", and 
should never be confused with the "node name", and should never be (directly) 
used for identifying the agent to the master.  The "node name" is a completely 
separate entity (though historically wasn't represented as such), that just 
happens to default to the value of the "certificate name".

"node identifier" is the "node name".  After the changes that Nick and I have 
made will be represented on its own (though will still default to the value of 
the "certificate name").

The pre-existing "node_name" setting only confuses matters, and should be 
deprecated under its current name, since it isn't actually about setting the 
node name, but about how we generate the list of "fallback node names" to use 
when doing node lookups on the master.  (See: `lib/puppet/node.rb`)

Feature #2128: Allow arbitrary fact as node_name identifier
https://projects.puppetlabs.com/issues/2128

Priority: High

Target version: 2.6.x

Currently, the only fact available as a node_name identifier is the hostname.  
I would like to have the capability of having any fact be the node_name 
identifier.

Use Case:

The reason this discussion came about is EC2.  When an EC2 node is brought up, 
the hostname is not known.  If we were to have a large, auto-scaling 
infrastructure, it is currently very difficult (impossible?) to automate 
bringing these EC2 nodes into puppet.  

One possible solution is to allow any fact as a node_name, and then for each 
particular EC2 instance type that one would need scaling (apache, memcache, 
mysql all come to mind among many others), the AMI would be customized with a 
custom fact.  An example could be a fact called "hostclass" that would then be 
set to "ec2_apache", "ec2_memcache", or similar.  This allows the auto-created 
machine, which we would otherwise be unable to differentiate from any other EC2 
node, access to puppet in an automated way.
