Hi, first author of the paper here. We also consider this as part of the increasing arsenal of smart-home attacks, which can be opportunistic and long-term. Also given that it's an offline attack, as signal processing / machine learning methods improve, perhaps the lidars signals an attacker collects could eventually become intelligible audio. I was also surprised that they don't have microphones. I guess the developers would prefer to have that on the companion app instead.
