I assume they need to do a bunch of WebAPI bullshit to get around Youtube's draconian policies, but maybe one day https://txikijs.org/ will solve all problems with embedding javascript. I believe, and maybe the strength of my belief will be enough.
Bun was just one of multiple JS runtimes supported, so dropping them doesn't have user-facing consequences. The people posting militant comments here and harassing the maintainer on GitHub are fighting for Anthropic instead of trying to raise any legitimate concerns about yt-dlp.
