Today, in almost case, we don't have to write for loop because native implementations which supports
iterator protocols or you might use some down-level transformers. So I think we should enable this rule.

If your application cannot use any down-level transformers or if you face to some perf issue,
let's disable this.
If you would like to ban for-of loop by that the transformed code is large,
then it might be more better to ban for-of syntax.

However, by the implementation of this rule v1.7, this mis-reports the error even if the collection in for loop does not have Symbol.iterator().
