The context here is an introductory course for Python. So there is not
"the algorithm", there are all the algorithms that a novice is likely
to encounter.
For me it makes absolute sense to base the contents of the course on
popularity. Constructs which a novice programmer is very likely to use
or encounter in other people's code should be covered more thoroughly
than constructs that will be used only rarely. Some are so rare that
they can be safely omitted. The while loop is certainly not in that
category, but it probably makes sense to spend less time on it than on
the for loop.
