You can put a lot of pressure on your ski through your boot and this means even some torsionally very stiff seeming boots will start to twist. So using cables means that the whole boot sole is tightened up again and your level of control is not diminished as you turn even in the worst wet, heavy snow. Unfortunately, cable bindings, by stiffening up the boot sole tend to restrict heel lift, because they restrict the ease with which the boot heel can rise off the ski. This means more tiring flat touring and possibly a greater liklihood of blisters, which you obviously want to avoid at all costs. Cable bindings, then, are generally used for piste or steep skiing where flat touring is not involved.
Heel lift becomes less of an issue and the cable's benefits really shine - more control.
If you do manage to rip out the pin holes on your boots, it is time for drastic field repairs to get you home. Or how about Voile's 3-pin cable. Stick it back on for those turns coming off a hill for more control. There is no hard and fast answer to release bindings, but we feel that there are enough inherent objective dangers when ski touring or telmarking without adding dangers through poor equipment choice. However, when out touring in the hills we always use releasefor all the extra weight of a basic Voile release kit, we would rather have the increased safety margin that it offers.
