I see.  Since the consensus seems to be that the application should be
controlling the deadzone, I'd be all for leaving it up to that, conditionally
to whether the app does it well!  A good point was made at the link I offered,
which is if the application employs any math to calculate a variable deadzone,
then a presence of a lower-level deadzone would skew the results.  My only goal
in using the js device node was to use 'jscal' to actually eliminate the
built-in deadzones at the time.
