Important note: the "some" is because we seem to only be able extend Python's json library in a way that lets us convert string values within JSON objects (e.g. '{"lastModified": "2019-07-25T14:35:51"}'). Strings outside of JSON objects (e.g. '"2019-07-25T14:35:51"') will not be passed through our decoder. (N.B.
