I am not advocating using SPAs of any kind, especially in a blog context. However, if there is a library which makes it easy to render MathML, why the hell wouldn't you just use it?
I'm not saying that I've never invented artificial constraints for myself; arbitrary goal posts that literally nobody but me would ever notice much less care about. I am saying that perspective is everything, and that sometimes it can be hard to see from the inside.
This is intended as an expression of care.
