What I mean is "really need". In fact, there is also the possibility we want to highlight a portion of an image, copy a subimage, etc, but did our HTML <img> tag designed like the way I mentioned?
I am the author of a math search engine OPMES (tkhost.github.io/opmes), the search engine works pretty well without the knowledge of DOM structure of math expression.
Actually MathML makes a lot inconvenient during OPMES development, to a degree that I choose not to support it.
BTW, if we want a <math> tag that no one will write by hand and only machine will try to understand, then think about why not HTML being designed as some open binary format in the first place?
