An embedded map is definitely a document. The problem being that this document is too large to fit on your computer, so it needs to be stored on someone else's computer and therefore can only be accessed piecemeal.

What prevents one from sending a screen size and getting a server-side rendered SVG back with that exact screen size? It was a thing in Telnet days, and it's what Stadia/Mighty browser are doing. Not that I'm saying it's a good idea, but it is feasible.
