Nice, I assumed it only would change the encoder to utvideo and the sort and didn't bother touching it. Additionaly, key frame segment splitting almost never results in equal chunks.
Technically you are correct, however it's mostly close enough (within a few seconds), so I didn't put it in a separate category.
Personally, I would rearrange it as third option and call it:
Splitting Mehtod: Key Frames
Neither the current arrangement, nor calling it segmenting, would be as expressive.
Most videos I re-encode are AVC Videos (MPEG-4 Part 10) and given, they were encoded with x264, their key-frames make for proper cutoff points already. Thankfully, FFmpeg has an inbuilt segment muxer: https://ffmpeg.org/ffmpeg-formats.html#segment_002c-stream_005fsegment_002c-ssegment
For example, I use the following line and use the output files in a batch folder for NEAV1E as a parallel encode:
ffmpeg -i input.mp4 -c copy -f segment split%d.mp4
No prior re-encode needed and, depending on the video, can be more reliable than even PySceneDetect.Segment splitting would be a useful third splitting option for NEAV1E.
