Today, every people know the distinction between cross country skiing and alpine skiing. And nobody will say stupid thing like we both are on sky, weir winter equipment, etc. the difference is obvious, more than in our sport.
Telemark turns is an old technique not in use today by most people. We can imagine people at that time who had to travel accross long and steep hill using snowplough turn on that ground. As the people become more aware of telemark, a new ethic was used to go downhill. The last step of the evolution was our new rigid both and fixation just use to go down hill.
In climbing, I can thing that we are at the telemark time to make the distinction between two kind of practice. It is easy to imagine that going with alpine equipment in a trail going up and down is ackward. I just can hope that beginer will understand that going to and adventure area with bolt and gym technique can be dangerous.
