-A potentital danger:
-
-Overriding generated formats is possible (see CustomFormats), however it can be
-easy to forget to include the custom formats.
-=> In that case, the program will still compile, however it won't use the
-   correct format!
-
-Possible workarounds?
-
-  - Require explicit format declarations, i.e. remove implicit from `implicit def
-    gen[T] = macro Magnolia.gen[T]` and add `def myFormat = gen[Foo]` to every
-    format trait.
-    => requires manual code, thereby mostly defeats the advantages of automatic derivation
-    => (advantage, no more code duplication since macro is expanded only once)
-
-  - Avoid custom formats.
-    => entities become "API objects", which will be hard to upgrade in a backwards-compatible, yet idiomatic way
-       (E.g. new fields could be made optional so that they won't be required in json, however the business logic
-       may not require them to be optional. We lose some typesafety.)
-       => we'd likely have an additional layer of indirection, that will convert "api objects" to "business objects"
-          implemented by services
-          => Is that a good or bad thing?
