With the epub 3 standard also mathml is supported and when a reader is used which doesn’t understand it that’s no problem because the standard is AFAIK backward compatible and unknown functions are just ignored.

In that case some postprocessing has to be applied to as it makes no 
sense to add tons of code to context to produce a less rich output (also 
a pain to do and it will never be ok). We would end up with ugly kludges 
like misusing <h1> for whatever we like combined with classes that make 
it titles, section numbers, inline highlighting, etc ...

The export is not so much html but xhtml and afaik css can deal with 
that. I woudn't be surprised if future ebook devices could do the same 
as what firefox/chrome do. Also keep in mind that the (now xml) export 
can be converted while some html/class/span/div hybrid would be painful 
to postprocess. Going from rich encoding to poor encoding (rendering) is 
easier than the reverse. I can imagine that we provide a couple of 
mappings from export xml to whatever html.
