Yes, I agree with you on this. I like Isaak Rubin, the godfather of value-form theory, quite a lot. Incidentally, he makes the point I made in the mammoth post I just sent about the impact of demand on necessary labour time, and his 'Essays on Marx's Theory of Value' even illustrates with Marshallian supply and demand curves.

It's no accident Rubin was a great interpreter of Marx, because he really knew his history of economic thought, and therefore understood exactly what was novel in Marx and what was part of the classical background.
