MathJax may be your friend. LaTeXML and katex do not add <mrow> as well.

Actually I asked to confirm that your troubles are not with proper 
escaping of input to a converter.

I have not used katex before, I just noticed it in

During my quick try of LaTeXML I learned that "--preload=siunitx.sty" 
should not be used with fresh TeXLive despite it is recommended in the 
`org-latex-to-html-convert-command' docstring.

I have seen <semantics> as well, but I did not go deeper. I recall the 
following in the context of screen readers:
