I believe VFR should be very useful for content types like animation, where real framerate might be 2-3 times lower than the nominal one. Or for hybrid content, combining 25 and 30 fps videos, so that there will be no need to use 120fps videos like people used to do for a while already.
You might want to take a look at Dup and DeDup filters of Avisynth, they are supposed to generate timecodes file to convert CFR to VFR.
