Is it safe to remove the declaration of a form from the unit?

When designing a TForm, a line is added to the form's unit declaring the form object...

var
  frmMyForm: TfrmMyForm;

I don't need this form auto-created, and I intend to create multiple instances of it, and to make sure I don't make the mistake of using this declared form, I commented it out...

//var
  //frmMyForm: TfrmMyForm;

I was wondering if this is safe to do? I don't see any problems, and the form designer still works fine. But could there be some trouble if I leave this out completely?
