My point is precisely that there are no known metrics which are
both useful and computable, and not even a theoretical
framework exists that could lead to such metrics.

Go has metrics "thickness" "influence" "alive" "dead" "heavy"
"overconcentrated" etc, but they are all essentially uncomputable.
Conversely, lots of computable things have been tried as proxies
for the real metrics, and none has been shown to be much use.
