ClF4+ Lewis Structure

Why does the lewis structure for ClF4+ place a formal charge of -1 on the central Cl atom when you could double bond one of the F atoms and move the formal charge of -1 to one of the non-central atoms?

I think F only forms only single bonds because of its electronegativity

Additionally, emember that F isn't one of the atoms that can have an expanded octet so moving a lone pair from Cl to form a double bond with F wouldn't work.
