In the techniques of BC skiing, making turns is not essential. Moving safely and efficiently across the terrains comes first always. For that purpose, you may need to review the basics of XC techniques as described in the basic section of the Australian Nordic Ski Manual.
Direct descent shouldn't be underestimated. That's the basis of all downhill techniques. Always anticipate sudden change of terrain and snow conditions. Right before those changes occur, take a telemark position. The width of the stance and the height of the positions would depend. Keeping your abdominal pressure high is a good way to counter those changes also.

Look scary?
That would happen to you, also.

However, you don't have to go overboard like above video.

That would be left for advanced XCD skiers.

Shuffling your feet during direct descend is a very good practice for getting a sense of flotation on powder.
If you get a knack of riding on skis, that means you have mastered 80% of all the XCD techniques.
