One behavior difference between multierror.Append and errors.Join is that the former will append to an existing multierror if it is (so the new one has a length of N + 1), while the latter will create a new joinError which includes previous error and the new one (so the new one has a length of 2)

I feel the expected use pattern of errors.Join is to have a errs [] error to save all the errors along the way and a errors.Join(errs...) at the end to produce one joinError.
