+# Historically, recipes were treated as simple Python dictionaries. This made sense because Pyobjc gave us a natural
+# toll-free bridge to convert between Plists and Python dictionaries. Recipes were essentially parsed into dictionaries
+# and everything was treated as functionally strings.
+#
+# However, there are many problems with this approach. For one thing, plists can nest dicts and that makes type checking
+# in particular rather challenging and unwieldy. It's flexible, but the lack of type safety is one of the big design
+# limitations in AutoPkg's error-handling. AutoPkg basically can't produce meaningful error messages at runtime because
+# it can't realistically predict what types of data it's getting from a plist.
+#
+# To address this general problem and allow AutoPkg to more safely handle different scenarios, we're going to reduce
+# the flexibility a bit by instead converting Recipes and their contents into actual objects.
+#
+# Generally speaking, all Recipes follow a specific structure and have generally immutable top level keys. By
+# turning this into classes, we can guarantee the keys we care about exist, and we can type-check the values to
+# validate a recipe will be safe to run before we even do anything about it. This will allow AutoPkg to expose much
+# more meaningful error modes to the operator rather than just Python stacketraces.
+#
+# Recipe Trust info, a unique feature of overrides, is now using Python 3.7's dataclasses feature. Dataclasses
+# are mutable namedtuples, which themselves are like mini-objects that have named attributes. Since we're never going
+# to add arbitrary keys to these objects, they're a perfect fit for this use case. Parent Trust always has a fixed
+# representation.
