I agree with the last part but suggest that actively drilling the "break and escape" options reinforces the idea that this isn't a "fight" per se. The object is to minimize risk for all concerned via whatever pragmatic means, rather than to win in the conventional sense. Obviously, the best tactic is always going to be situation-specific.
The breaking and escaping is pretty easy to drill, and I have found that it is almost not necessary. When you spend a lot of time doing the more advanced techniques, steping out or away is a simple veriation to almost everything. Once you have control, backing away is easy. Getting control is the hard part.
