There are 2 uses of the hashes in bittorrent. a) integrity checking b) as unique identifier for the swarm.
The hash only gets truncated when used in places as unique identifier. When you start with a v2 magnet link or torrent file you get the full 32bytes hash, which means your integrity-checking is unaffected.
