But in reality not all feature dimensions are orthogonal. You can't make the same 'adjustment' for any potential trait bias. Correcting for the purple/orange thing might skew the data on square and round heads, and correcting for that might skew it on pointy and rounded ears and so on and on.
The intention is laudable, but many a road to hell is paved with good intentions.
