 It should be difficult for someone to partially (for a substring of the hash output) find a collision or "second" pre-image.
 
-- Bitcoin PoW is a partial pre-image attack.
-- Prefix/suffix pre-image attack resistance reduces opportunity for UI attacks for address spoofing.
-- Prefix collision resistance important to rationalize costs for some cryptographic data structures.
