I got some feedback from authors of good looking DVD rips:
"Used the Yatta software, in which you can detect patterns and enforce them (for the 3:2 sections) as weell as do other manual stuff like freezeframing the cuts where one field is missing and you can also select the 30fps sections so that they don't get decimated, the software generates timecode files for you and the end file is VFR then - 24fps where it was IVTCed and 30fps elsewhere.
It was an awful lot of work to do it that way (besides watching out for 60i fades done on top of the ^ and having to apply debanding in places)"
Yatta software is some very special Avisynth tool https://forum.doom9.org/showthread.php?t=161653
So it is possible to autodetect those variable telecine patterns, but it is not a one click workflow.
There is also YATTA for VapourSynth (real name: Wobbly) https://forum.doom9.org/showthread.php?t=172496
