You have replaced a definition that was easily understood by most people, by one that can only be understood by mathematicians.
I know what covariance means, and I was once familiar with how it is calculated - and I find your definition absolutely incomprehensible.  Just imagine how unhelpful it would be to (say) an economics student who needs to understand financial risk analysis - as a practical tool, not as an intellectual curiosity.

You have replaced a definition that was easily understood by most people, by one that can only be understood by mathematicians.

I know what covariance means, and I was once familiar with how it is calculated - and I find your definition absolutely incomprehensible. Just imagine how unhelpful it would be to (say) an economics student who needs to understand financial risk analysis - as a practical tool, not as an intellectual curiosity.
