Why is lscr.io's Jellyfin so keen on storing subtitles?

For the subtitle issue: If you don't use subtitles, delete all the triggers for subtitle extraction to stop it from happening at all. Or change the trigger to something more appropriate like 1 AM with a limit of 7 hours (for example). If you don't care, turn it off by deleting all triggers. I think TDP has the rest covered. Just figured since I use the LSIO image I'd chime in.
