What are your suggestions for improving BFI?

BFI is here to stay, and I hope it becomes standard someday, when it's good enough. Flickering technology in general simply handles motion better than sample-and-hold, and that is true for all frame rates: from 24FPS in film (reducing stutter and making the motion look smoother), to higher frame rates in videogames, like 60 and 120FPS (reducing motion blur, and also making the motion smoother). BFI is crucial in VR as well, because while the flicker can cause headaches in some people, a far more common cause of headaches in VR is excessive amount of motion blur due to image persistente from sample-and-hold.
But there are still plenty of criticisms, misinformation and inconsistency in how BFI is applied.
So, my question: what do you think should be done to improve BFI in all aspects for all sources? To maximize the smoothness and clarity of movement, while minimizing any discomfort from flicker, and also not make the brightness take a huge hit?
Should OLEDs just try to emulate the look of traditional old film projectors, which flickered at just 48hertz (and gave a much smoother motion than OLEDs with BFI turned off)? But then I see a few people saying that even 120hertz flicker in BFI makes them feel ill a bit! I don't get this, CRTs flickered at only 60hertz! Can we find a way for OLEDs to flicker at higher refresh rates than 60hertz, and in the exact same manner that CRTs did? What is exactly wrong with many modern BFI algorythms?
Above all: I just want movies to look like they're supposed to: no stutter, but also no soap opera effect! There must be a way to achieve this, based on all I said above.
