I see references to it in the SX1231 datasheet as "low battery indicator" and "low battery detector." http://www.semtech.com/images/datasheet/sx1231.pdf
However, I don't see any similar references in the RFM69 datasheet.
Is it worth exploring? If so, has anyone done any exploring of it?
The RFM69 does not support RegLowBat and related commands. Are you sure you are looking at the right chip specification?
Yes it does. The chip in the RFM69 Hope modules is the SX1231H. Check the datasheets.

Good catch! I won't be able to test this right away, but would be interested in any results anyone else finds.

The RegLowBat, related commands and corresponding DIO0 interrupt mappings were removed on the SX1231H variant.

Yes the RegLowBat was, my bad. On the H chip the register is still there and it's "Reserved0C".
About the DIO0 mappings, i see them on page 48 (http://www.semtech.com/images/datasheet/sx1231h.pdf).
