- MathML as a spec is akin to SVG, it's meant for the browser/machine first, and not for direct human consumption. You don't read/write SVG by hand, and neither you should MathML.

Sadly that's not true for SVG. SVG has many parts that are only there to make writing/editing SVGs by hand easier. Circle, rectangle elements, the commas in the path strings (which follow relatively insane rules. Almost all implementations already had bugs in the correct parsing behaviour regarding commas/whitespace)
