I agree with all your points!

Regarding the bootstrapping process: we could already split the
packaging tutorial into 2 "recipes":
- A guile primer
- The actual packaging tutorial

Of course we would interlink them.

Once done, we should not forget to update the blog post to let the
readers know to refer to the corresponding cookbook instead.

Out of curiosity, can you remember which part of the tutorial is out of
date?  I cannot think of anything.
