I think once the standard is fully implemented across browsers authors will be able to define a font-family and the results should be visually similar in all browsers. I think this is preferable to authors in case they want a specific font family that matches the overall design. As an example take a look at my doc page for MathUp[1] in firefox (which supports MathML natively). I am able to use Libertinus as my main font family and compliment it beautifully with Libertinus Mono for code samples and Libertinus Math for the math samples. 1: https://runarberg.github.io/mathup/ https://runarberg.github.io/mathup/
