I don’t see how riddling content with markers to do syntax highlighting would fare any better than the current span soup approach.

I personally see more benefit in something like a `<script type="highlightmap" id="my-highlightmap">` + `<pre highlightedby="my-highlightmap">` in which the browser would do it all by itself. Extra advancage here is that it is perfectly polyfillable, and it would play nice with static HTML that, for example, gets generated from an MD file.
