I fully and completely endorse this idea! The practice of
embedding reusable data in HTML using <script> is wider then JSON-LD, or
Turtle. Almost all the issues are the same. Also as this is a
new emerging practice it makes sense to be able to rapidly change our
advice in the face of implementations.
