I dissagree with your dissagreement.

It doesn't just remove Dune from hard-sf. Even a soft-SF author righting the same book nowadays would make some changes to OM, they would likely attribute it to QM, or metaphysics. They would have to be seriously amature to say that the memories are stored in the DNA, because it's common knowledge that it doesn't work that way.
It's not the fact that characters have ancestral memories that dates Dune, it's the fact that these memories are coded in DNA.
