Supplied templates roles in Hydrogen v2? demo-store vs skeleton vs hello-world

[tarikjn]

Hi, is there documentation anywhere explaining what are the roles of the demo-store, skeleton and hello-world templates?

Hydrogen v1 doc says demo-store is the default template and hello-world is a minimal template: https://shopify.github.io/hydrogen-v1/tutorials/getting-started/templates

But in Hydrogen v2, skeleton is the default template loaded by the CLI.

But, demo-store seems more complete and appears to include analytics, which is what a dev would expect the default template to provide (same functionality starting point as Dawn liquid theme)

Also, skeleton's README.md says its a minimal theme, so what is the difference with hello-world?
