Only as a user that once briefly tested the same option with yadif.
If the video is flagged per frame as interlaced / progressive then it
appeared to respect that.
The BBC broadcast their DVB-T2 HD H264 like this in the UK, and ffprobe
-show_frames will report interlaced or progressive per frame.
Some programs are a real mix, more often the content is all progressive
and then the credits at the end interlaced.
In my test I used yadif=1 so field rate like w3fdif produces and the
result is then a mixed rate video.
