As PZL 104 pointed out, that’s the way MFS allows to somehow model control forces, and the “difficulty” an “average muscled” pilot will have to fight those forces with increasing dynamic pressure. I see no problem with modelling this and it’s actually a positive aspect provided they do it as sound as possible.
Simulators like DCS and IL2 have their own approaches too. None is totally satisfactory, each one has it’s own limitations, but that’s the price we don’t pay for sophisticated controllers, like those used in commercial simulators that is to be blamed…
Ideally a simulator like MFS or X-Plane for that matter, should easily be able to communicate these forces to the controller HW, and it could then use hydraulic, … systems to reproduce the forces on the controls, but just imagine how much we would have to pay for such fancy stuff…
