I don't see why making it recursive algorithm makes it easy to change the
number of tasks. The non-recursive one is as easy as or easier than the
recursive one to change that.

6 line code is apparently better than recursive long functions. My point is
that if there are two ways to do something similar, we should always choose
simpler one.
