And as bonus there is no temporal hole where you could access a null or dangling text.

Here it is as a runnable snippet: https://godbolt.org/z/fc4Gfxrfd

In cake there is no temporal hole, we cannot reuse the deleted object. This prevents double free and use after free.

    int main() {   
       struct X * owner p = malloc(sizeof(struct X));
        
       p->text = malloc(10);

       free(p->text); //object text destroyed

       //p->text is on uninitialized state. 
       //cannot be used (except assignment)

       struct X x2 = {0};

       *p = x2; //x2 MOVED TO *p

       x_delete(p);
