XML and readability are orthogonal concepts in the end. Basic html is easily editable and readable by humans. There is nothing preventing them from making an actually human editable XML markup language for maths. And that is the sad part.

As MathML is not human readable nor editable it’s effectively an opaque image format that can be manipulated from JS side and that scales like vector graphics.

Yep. MathML is quite similar to SVG in that it's really hard to write by hand and you need editors to make it accessible.
