I think it would be cool if there was a section for segmented runs and tases in speedrun.com. You could put it under leaderboard and have a section for it there. It would be cool to see how long it took to create and all the people who worked on them. Just a thought that came to my head

Why? Segmented runs are not competitive and there is precious few of them. If you want a single place to have them all listed, someone could make a Google Document but realistically, all you have to do is look at SourceRuns Youtube Channel https://www.youtube.com/c/sourceruns/videos

Not for competition, but just so there is a easy way to access it if you are speedrun.com
