Not providing the recipes as an importable API is a deliberate design
decision, as what folks often need is code that is
similar-to-but-not-exactly-the-same-as the code in the recipe. If they've
copied the code into their own utility library, then that's not a problem -
they can just edit their version to have the exact semantics they need.
Individual recipes may occasionally get promoted to be part of the module
API, but that only happens on a case by case basis, and requires a
compelling justification for the change ("It's sometimes useful" isn't
compelling enough - we know it's sometimes useful, that's why it's listed
as an example recipe).
