How do you prevent then any users deriving from your classes, from
adding their own destructors ? Their destructors might not be

How does this look in code?
struct A
{
    ~A() {} // non-virtual
    virtual void foo() {}
};

    ~B() {}
    void foo() {}
};

///////////
A* a = new B;
delete a;    // doesn't call ~B(), but should
