While these options can help reduce the number of requests needed or avoid some rate-limiting, they could cause some issues. See [#860](https://github.com/yt-dlp/yt-dlp/pull/860) for more details
 * `include_live_dash`: Include live dash formats even without `--live-from-start` (These formats don't download properly)
