This is yet another symptom of Java's fundamental design mistake of being
unable to simply inherit implementation, that we have learned to live with.
"Inheritance is not subtyping"
One way of inheriting "only implementation" is to have a package-private
superclass with public methods. (AbstractStringBuilder for example). It
confines all implementations (subclasses) to the same package though, so
it is not a universal tool. With jigsaw there is another possibility: a
public but internal (confined) superclass which is exported just to
modules that need to subclass it.
