Should the template set up logging?

Logging is one of those things every app will need sooner or later. Should it be set up in the template? To what extent?

* No logging in the template
* A comment in the appropriate place (`main()`) saying something like: "Here's where you can set up your logging and error reporting" (plus link)
* Use `pkg:logging` but do not gather the messages
* Use `pkg:logging` and gather the messages in `main` through `Logger.root.onRecord.listen`, printing them
* Use some other approach

Start at the template's main() entry point and review how pkg:logging and Logger.root.onRecord.listen would fit there. The issue presents several competing approaches but records no decision; done would require a maintainer-approved logging scope and an agreed implementation or documentation change.
