I honestly believe that the grandparent comment didn't have such intent in mind. However, even though OP likely didnt have such intentions, I agree with your overall assessment of what would happen.

And for that reason (+a lot of other unwanted second-order effects others have mentioned), I am definitely not into the idea of such zoning at all.
