In my opinion, browsers should not be promoting non-standard usage of W3C
technologies as you have just described.

So make your index pages HTML, and inform your readers that they will need
more recent browsers on those pages, then link to your text/xml pages
with the text and maths in them.

This is just like the many sites that have PDF documents on them but use
text/html index pages to link to them, with the index pages informing them
that they will need a plugin to view the documents.
