It seems you really have some difficulty on this. Yes your way of sailing should be adapted to each boat characteristics and not otherwise.
Each boat has an optimum way regarding being sailed effectively. Not all are the same. Some are more effective upwind with more heel, other with less.
If a boat does not only reminds the sailor about the better and more efficient heeling angle but also makes easier to find it and makes difficult bad and less efficient sailing, preventing him to pass that angle it is worse or less flexible than a boat that does not pass any information to the sailor?
Let me remind you that on top of all this that chine increases stiffness at the more efficient angle of heel, making the boat go slightly faster.
It beats me how you can see any of this as negative but I will insist no more, have it your own way
