Description
If you lose the type argument for Codec (and superclasses) there's no way to tell whether it's nullable, which makes life hards Grackle, which constructs codecs at runtime and doesn't have this type information hanging around. So can we upgrade types: List[String] with types: List[(String, Nullity)]? Doesn't seem too bad, heh-heh. /cc @milessabin

Research direction
No file, test, or entry point is named. Start by locating the Codec metadata represented by types: List[String] and trace how Codec and its superclasses expose it to runtime consumers such as Grackle. Done means the metadata carries each type together with its Nullity, including for codecs whose type argument is unavailable.
