Agreed. Some version ago a "cosmic-gnugo" option was introduced (playing huge moyo following Takemiyia Masaki 9p cosmic style), and it was significantly stronger against standard GNU Go, but weaker against other opponents. As it is not an improvement (lose against other), this "microscope effect" at least showned a weakness in the standard version (not abble to counter a cosmic strategy). This is usefull.
