Some antisuji moves (eg in joseki) are attacks that work, but have bad
consequences (eg sacrifice a corner for overwhelming thickness).  We need
to be cautious about that sort of thing.  I think the appropriate response
is to have antisuji moves never be played, but be very cautious in
applying that classification.  I think revising large negative shape
values for vital moves is reasonable.
