"Do we really need to manipulate a math expression?"
If you don't, please don't say no one does. Having a math DOM allows for actual interactivity with mathematics, from highlighting, copying subtrees, embedding links, having on the fly computations/simplifications, etc.
Not to mention add-on services like math indexing and search.
Yes, we need to manipulate and machine-read math expressions, if we want to finally take online math workflows to the 21st century.
