Agree, we do not include a 4*4 image in HTML by inserting <img><row><col><pixel r="255" b="0" g="128" a="0"> ...... In browser level, I think we should treat math expression as a simple and atom component, and the only benefits to expose DOM/XML/JSON or whatever structural information in webpage is probably you can manipulate/extract info from it (e.g. using Javascript). Do we really need to manipulate a math expression? I think a simple "<math>\frac a b</math>" makes much sense to me. I think it is about the trade-off on HTML granularity.
