It's not in the class map because there is still an actual JArchive class. Maybe this can be considered for 4.0, but I'd be hesitant about that because there are some minor differences between the archive classes the CMS provided and the archive classes from the Framework package (i.e. the Framework code doesn't use static methods whereas the CMS code does) that makes mapping a less-than-optimal choice.
