Can someone explain why this is better than yt-dlp

Though there are some cases where using pure ffmpeg is just to difficult or impossible. Recently i had such a case where I wanted to merge multiple video files from my GoPro (they come out in 4GB parts if the video is longer than that), but while keeping / correctly merging all metadata such as date / accelerometer / gps / any custom binary streams. Ended up using this and worked great https://github.com/gyroflow/mp4-merge
(Also, a multitude of tools isn't really all that helpful if they all stop working in the same instant because they all relied on the same APIs etc)
The project was started in 2012, long before yt-dlp (but not before youtube-dl)
