errors.Joinは呼ばれるたびに新しいオブジェクトを作っていく https://cs.opensource.google/go/go/+/refs/tags/go1.20:src/errors/join.go

それはそうって感じの実装だった https://cs.opensource.google/go/go/+/master:src/strings/strings.go;l=1278?q=CutPrefix&sq=&ss=go%2Fgo

// CutPrefix returns s without the provided leading prefix string
// and reports whether it found the prefix.
// If s doesn't start with prefix, CutPrefix returns s, false.
// If prefix is the empty string, CutPrefix returns s, true.
func CutPrefix(s, prefix string) (after string, found bool) {
    if !HasPrefix(s, prefix) {
        return s, false
    }
    return s[len(prefix):], true
}
