Why does C++ not allow `new` to call constructor when creating arrays

Question

Lets say you are creating an array of objectes on the heap like so:

myClass * objectPtr = new myClass[10];

new only invokes the default constructor, and (based on my readings) does not allow any other constructor to be invoked.

Is there any logic behind why new cannot invoke any other constructor? It would seem better to do something like

myClass * objectPtr = new myClass[10](12);

as opposed to

myClass * objectPtr = new myClass[10];
objectPtr[0] = myClass(12);
objectPtr[1] = myClass(12);
...

It does. It is just a bit tedious:

struct my_class
{
    my_class() {}
    my_class(int, int) {}   
};

int main() 
{
  my_class* objectPtr = new my_class[3]{my_class(1,2),
                                        my_class(), 
                                        my_class(3,4)};
}
