The performance/cost/complexity envelope is the answer.

It is very simple to single step a stepper on a floppy disk drive or
other small unit. There are dozens of stepper driver designs around
because it is so easy to run them.

You've already mentioned the torque curves.

Feedback servo systems cost more in complexity with a minor gain in
cost, but a major gain in performance.

How does it go ? performance, cost, complexity, pick any two ?
