Review Comment:
   > Do you know if this change is safe? My cursory look indicates it may be 
ok, but I would have to look at this more carefully. 
   
   Since other similar cases pass immutable lists to `ControllerResult`, it 
seems safe to do so here as well.
   
   > I think we should also do this via a different PR (to avoid including a 
potential behavior change in the middle of this clean-up PR).
   
   make sense to me
