By not special-casing positions like this, you adopt the general
rule that they're no different from other positions with the same
balance of material. That's probably wrong more often than, say,
deducting half a pawn in positions "like this one" (whatever that
might mean). Every term in the evaluation of every chess program
(apart from things that handle forced wins and draws) represents
a general principle that has exceptions.
