RFC for Chef 12 Attr changes

I think I understand now - that this is actually more pertinent to the use case of "enumerate me all thinks in a hash, and do something with them" - like in your examples of patterns of rendering template config from any hash. Thanks for the explanation.

I don't know that the assertion in the paragraph below this one, "simple deletes no longer work as they once did." is accurate, since there never were explicit deletes, only implicit once with the override vs merge behavior. So maybe it was some of that verbiage that prompted my question.
