> A "batteries included" JSON log formatter would be a useful enhancement.

See

I don't propose to implement your suggestion.

You've now logged three enhancement requests where there are recommended mechanisms in the cookbook or reference documentation for dealing with the situations you describe.

I'm not really minded to implement any of these proposed enhancements, as I think the approaches already described in the documentation are adequate.
