It can be handy to ignore the Earth's rotation and simply work with the effective g', instead of accounting for g'=g+a; and similarly it may be handy to use Coriolis forces and so on for weather predictions. Nevertheless I assume that calculations with fictitious forces can always be reconverted in similar calculations without them, for the simple reason that they are based on Newtonian physics that does without them.
However, in recent discussions*, several people asserted that for particular cases it is necessary to introduce fictitious forces, or at least that introducing them significantly simplifies calculations of particular problems.
I invite those who agree with such claims to give specific examples here. Then we can put such claims to the test by trying to do similar calculations without fictitious forces.
