Hooking the video out of a computer to a TV isn't the only use case. Once you can stream to any device and multiples of them, transcoding on the fly, with a good UX that saves your spot and tells you what's new with artwork and what seasons or special cuts are available, each attached to user profiles for multiple people, with good search including in metadata, and toss in the ability to download subtitles on demand and whatever else, you will be well on your way to reinventing Jellyfin and other plex-alikes!

I understand favoring simplicity for a simple use case, but it obviously doesn't scratch every itch.
