Actually no apart from configuring the device at startup. Or configuring the device in genral without the need to wakeup. Maybe if there's a short time frame where you don't want to receive new packets for whatever reason.

> Will there be any noticeable gains in overall battery life time if we go to TRX_OFF while doing some internal computations after an RX packet instead of remaining in RX_AACK_ON, or instead of putting the transceiver to proper sleep?

I think this really depends on the use case, i.e. on the time it takes for the computations. 

Maybe you're right that we don't really need such a state.
