[FFmpeg-user] No frame progress on video stream copy

There seem to be a change from 6.0 to 6.1 that cause frame, fps and q to
*not* to be outputted to progress when copying video stream.

Simple minimum way to recreate:

*Using 6.0.1 build from master November 30. 2023:*
*  ffmpeg  -f lavfi -i smptebars -c copy -t 0 -f null -*
  *frame=    0 fps=0.0 q=-1.0 Lsize=N/A time=-577014:32:22.77 bitrate=N/A
speed=N/A    /s speed=N/A*

*Using 6.1.1 builds from master December 31. 2023 and January 28. 2024.:*
*  ffmpeg  -f lavfi -i smptebars -c copy -t 0 -f null -*
  *size=N/A time=N/A bitrate=N/A speed=N/A*

Is this behavior intentional or caused by a bug? Or is there some new
options I need to turn on in order to get back the missing data?
