I checked, no we don't NEED to change them.  We can, it works either way.  It does affect the help output. e.g.

Arguments:
        filepath :  The file path to the output file (FILE, no default value)
		
...which would be good as it's a  way of telling people these are FILEs therefore %p is interpreted, rather than just a STRING.
