Surely common sense dictates that you aren't going to carry out steep turns when you are too low, close to cloud, in controlled airspace or near airfields.
And why not, with maybe the exception of inside controlled airspace.
The steep turn is to teach a student to learn the safe co-ordinated use of the controls while maintaining accuracy, ultimately the time they are probably going to use this style of manoeuvre is as an avoidance manoeuvre from another aircraft, the whole object of instructing is to introduce the student to as many real situations as possible not hand hold them through the whole of their course.
