The point you're making is biting and socially justified, but if you can accept that there is some measure of intelligence/performance (it's probably pretty damn high dimensional) at least so much as to help explain why an avocado can't do software engineering, then it's worth considering that each new measure helps to get us a more complete understanding thereof.
Furthermore, if it's popular enough (which it probably won't be) then it becomes ammunition against reemphasizing the multitudinous aspects of intelligence.
So while the snark is pretty well deserved in light of the way people treat IQ... I say it's worth applauding further research.
