Items per_page variables

If we get an individual item we get variables relating to Committed stocks but not when getting items by page, will these eventually be passed here or am I better off sticking with getting the open sales orders & processing them this way as making 4000+ individual calls to get this data is unrealistic ?

Most of my behind the scenes processing is due to the fact that I don't want warehouse staff seeing monetary data in the modules so I don't allow them access to Inventoy, is this something you're working on guys ?
I truly hope so, as this will eliminate 90% of my back end code :-)
