If there's no information because the filters haven't generated data 
yet, (ie no bounds available), and a default value is not feasible (just 
can't be guessed sensibly), is it safe to update the inputs during the 
request information call and get the correct sizes? This is what I used 
to do, but I am not sure if the new pipeline will like it.
