Because it's not efficient if you have a bunch of edges to keep hard and if you still need to do some tweaking.
I discovered that the kind of result I want is reachable if I extract a region of poligons who's border share the edge I want to keep hard, then combine it with the original object, merge the vertices of the edges I don't want hard and then smooth.
But It's a tedious job too. Is there anywhere a split edge command?
