Backward compatibility, ie the ability to access archived data in legacy formats is really important.
I understand that the business case has been made not to support direct-read of these formats, but it would be great if we had a e00 to shapefile converter and/or a coverage to shapefile converter. This would give a path to load old e00 and coverage data into Pro without having to use ArcMap, or other software such as QGIS, GlobalMapper and GDAL, all of which can read these formats. Perhaps some of this existing open-source code could be used to create a conversion tool for Pro. Please consider this - lots of great old data sets are still out there in e00 format on the web.
