As a young Boy Sprout in the '50s buschraft skills were the main camping skills taught to us.
I learned about 5 knots and how to do several types of lashings to build outdoor structures.
First Class Scouts learned valuable fire-building skills and I even won a fire-building/water boiling contest at summer camp.
Axemanship was also taught, along with how too sharpen axes and hatchets. (I know,amazing, but we had no accidents in a troop of 30 boys.)
Also we learned to cook and eat local (Ohio) wild plants like bracken fern, skunk cabbage and cattail roots.
So I was fortunate to have learned those skills early. A few summers as a tall ship sailor taught me several other handy knots and even more as a Nordic and alpine ski patroller.
** Any good backpacking course should teach the following "bushcraft" skills:
>firebuilding
>map and compass skills (to a mastery level of competence)
>emergency shelter building (summer and winter)
>basic knots and bends
A basic 1st aid course should also be required.
