We will, and we reserved a set in ES5 while unreserving a larger Java-influenced set from ES1 days that actual implementations did not all reserve.

We may even reserve new keywords not in the ES5 future reserved identifiers list. But only with good reason and ideally where we don't break much content, or even any (think contextual keyword, e.g., new and meaningful only in class bodies).
