That is not true - there is nothing wrong with paths. Clearly the
audience would draw by copying or dragging such paths, not by typing
their syntax, but that is also the usual method for the rest of us as
well.

Yes, clearly, but the use of CSS in SVG does not cause the problems he
seems to think it does.
