Torrents wouldn't show "the exact contents of your video library to the entire world", only what is specifically being shared for the torrent. Also, in this case it wouldn't even tell anyone if you have the whole movie or not. XBMC allows media stubs (wiki) to be scraped, and various other things can use scraper data that don't actually lead to watching the movie itself (pull metadata for trailers, listings, etc).
