h1. Background 

 Workflows produce a lot of Specify if intermediate collections.    For production workflows that are rarely re-run, the job reuse benefits are minimal, instead this output is just clutter and takes up storage space that the user would rather not pay for.

 Intermediate collections need to live as long as they are in use by downstream steps, but no longer. 

 Should be able to specify default behavior (retain temporary or trash) but override behavior for output of specific steps. 

 not.
