Duplicate error from SA6003 and S1029

[arp242]

For the code:

package main

func main() {
	val := []byte("...")
	for _, c := range []rune(string(val[1 : len(val)-1])) {
		_ = c
	}
}

Two identical errors are given:

% staticcheck .
main.go:5:2: should range over string, not []rune(string) (S1029)
main.go:5:2: should range over string, not []rune(string) (SA6003)

Looking at the -explain for S1029 and SA6003, the checks seem very similar, if not outright identical? Either way, I wouldn't expect exactly duplicate errors.
