I agree having worked directly with it (long personal project). Photogrammetry is so error prone (get a sign wrong in your sensor fusion/SLAM code and you're cooked for 2 weeks) and I got into it right in the last years before models that could compete were introduced (reactions from PhDs who spent years working on photogrammetry were not nice as you can imagine). Once the models came out they were set to take over, I remember being blown away from the quality of depth maps alone.
