So what.
The whole idea of viscosity modifiers are to have a more ideal oil viscosity at all temperatures...
Which means that if you accept the idea of them shearing, you have defeated their purpose in the fist place, and will have to run part of your OCI with an overly thick oil.
Better off to pick a more shear stable thinner oil and be done with it.
