  Even this is not sufficient information to re-flow the design as many users prefer larger screen objects or may simply be unable to use your application due to vision problems or other disabilities.

      Certainly but you need to consider how your UI responds to a more (or less) constrained space as the zoom changes. It's hard to implement designs that adapt to that with the tools we have right now.
