As every sim the last 10-15 years have had support for force feedback, not including it in THE definitive flight simulator engine designed to last for 10 years is naturally impossible. Oleg may have issues with how the API:s work that are justified but if they did not include that it would be suicide for the product... Even crappy arcade flight games sold right into the bargain bin has it - and as stated here it is a vital immersion booster for many of us, especially the ones with IRL experience that are used to feel the stalls coming like you say. I would never buy a joystick without it (G940 owner myself and previous MSFFB2 user).
Do not worry about this as it's a waste of time
Edit - the same goes for TrackIR support. Once you have tried it - you can't live without it... And it sure will be implemented with all bells and whistles in CoD
