For example, would it be easy to write a shell script that starts a uniquely named nodelet manager and assigns a single nodelet to it? Call such a script "rosrun_nodelet" for example. Then you could run a single piece of code as a nodelet or a node.

As I understand it, that's exactly what happens when you run a nodelet
as 'standalone'.
That's what I was getting at with my question originally--why bother
with nodes when you can have standalone nodelets?

Very easy. You don't need a main function at all:

rosrun nodelet nodelet standalone your_pkg/YourNodelet

(or the equivalent in a .launch file)
