Well, we specified doing this from the start. Truncated pdu-in-error can happen if the original pdu was close to the MTU already (e.g. unitdata, RIM messages). Since the BVC is established end-to-end we need to route the STATUS correctly so the offending side can take action and/or report the issue.
