This is not about copying delegates. Consider the
example in the vala tutorial:

  delegate void DelegateType(int a);

  void f1(int a) {
      stdout.printf("%d\n", a);
  }

  void f2(DelegateType d, int a) {
      d(a);       // Calling a delegate
  }

  void main() {
      f2(f1, 5);
  }

This example compiles with no problem. But if we make
f2 async, i.e.,

  async void f2(DelegateType d, int a) {
      d(a);       // Calling a delegate
  }

the warning appears.
