I work in both GIS Consulting and Geospatial Education at a major university. In both instances, though somewha different scenario, it would be a nice to have the ability to print (or save as a jpeg and/or pdf) any and all geoprocessing messages and histories. in doing this, the geospatial practioner (be it a consulting or a student) running 1 or more geoprocessing tools can provide a report (of some kind) to provide the client (or professor) that would indicate the entire processing results. I get that there is a rather simple work around by just taking a screenshot of the message and/or history pane, so this is not a critical issue, but one that can provide integrity to the results of any and all geoprocessing.
