For me, those features were always very gimmicky. When you arrive at the gym, you should've set the basal rate lower at least an hour ago. So it's not going to help unless you stay for multiple hours. The meal detection mentioned is similarly lagging behind. For people who don't manage to tell their APS when they eat carbs, yeah it helps, but the outcome is not comparable to dosing before you eat. I also found the calibration features to be too fiddly. Between sensor noise, sensor offset, and calibration, when they try to adapt the situation already changed. I guess these features work better with a very regular lifestyle, which I lack :-) And while I don't like having to micro-manage some aspects, like carbs, I appreciate that AndroidAPS reduces my mental load quite a bit and enables living days that are never the same regarding exercise or meals.
