I think, actually, we can go one step further. A bunch of applications on the Web generate HTML on-the-fly based on data that is available to them in some sort of a database that is either JSON based or can provide JSON data. For those companies using embedded JSON-LD is the simplest way of expressing structured data.

B.t.w., there is also a symmetry with the turtle-in-HTML that is already a non-normative part of the Turtle syntax document. A consistency with that one is a good thing...
