There is another reason to use 10° flaps - training.
Many students are not learning to fly a 172, but using a 172 to learn to
fly
airplanes. If you are anticipating transitioning up ASAP (as in career
oriented students) it's good to get into the habit, because your next
airplane may require flaps on takeoff, and the one after that certainly
will.

I've noticed that airline pilots who also instruct in small airplanes tend
to
insist on flaps on takeoff, as a matter of good habit forming. Some also
call
positive rate and gear up as anticipated training.

Then again one could transition up to a real airplane which of course would
have no flaps. Nor would the one after that or the one after that.
