Well, according to comments from Dr. Hyatt, pawn structure evaluation seems to
be his major tuning focus for Crafty these days.  Clearly this is a worthwhile
goal, since computers are already top notch at tactics.  But the consequences of
pawn moves are often far too deep for tactical evaluation, so things like this
have to be caught in the positional evaluation.  A program *should* be able to
"see", just as a human can, that white has a great pawn structure and will
continue to annex space if f5 is allowed.  Not easy to program I suppose.
