There are plenty of people who do a few track days with the 3-point. It's just a matter of how far you want to go with a harness, which you need a mounting point for. There are people who will use a 4-point, which Schroth at least says is compatible with a HANS. There are people who use a 6-point, for which you need to install more mounting points anyways. The harness not only is used as a safety device, it is a driving aid. The difference between holding yourself in a seat over 15 laps and having a tight harness help support you, and keep your butt in full contact with teh seat, is night and day.
But the further you get away from using the airbag+3-point safety system, the more you introduce other potential problems, namely what to do with your head safety. THere are many different views on all this, but the one that persuades me is that if you use a full 6-point, that will keep your body in check in a frontal impact situation, then a HANS is a very useful device to have. It will keep your head from snapping forward as your body is fully restrained versus the intended function of the airbag+3-point which is designed to allow your body and head to go forward and then be cushioned by the airbag. Two different systems with different ways of protecting you.
BTW, Lotus has made seats in the S260 with HANS cutouts, I believe. A HANS fits just fine using an unmodified Exige seat as well.
