The 802.15.4 ack is basically a phy ack. It tells you that the bits were received, but that is all. It doesn't tell you that the incoming message passed any security checks or if the receiver has space to buffer it. The 802.15.4 ack has no security and no source address.
As FYI, the 802.15.4e TG is actively working on resolving these issues with the existing 802.15.4-2006 ACK. Regardless, however, I still see benefits in a 6lowpan-layer ACK.
