Travis, My read is that even if your not in a seismic zone you need to follow all the other hanging and bracing rules. Since it's laid on the truss there is no HANGING but it still needs to comply with the 40'/80' BRACING rules. Then again I'm about to be shaken into the sea at any time so I brace seismically without as a matter of habit. As to your actual question I'd say on my liberal side that if the hangers aren't being used for anything except alignment then it doesn't matter, my conservative side says that since they look like a duck I'd expect them to act like a duck and so since they don't quack I'd remove them to avoid confusion, and finally my wacko AHJ side says that since they have no standard (standard as in NFPA 13) derived function then they're not part of the system and so they must be removed as a non-system component attached to the system.
