Triggers for original Estimote Beacons

This blog article mentions expanding the SDK to enable triggers for the original Estimote Beacons in additional to Nearables. Looking through the SDK, though, the only rules I see related to devices appear to be rules derived from ESTNearableRule.

Were triggers ever expanded in the SDK to support Beacons? If so, where can I find such an example?

Any tips or pointers would be greatly appreciated!
