I think any artistic free-software tool *should* be doing likewise. There's a reputation that they're not as good as the proprietary competition, which this helps determine whether that's the case and how to fix it!
Pepper & Carrot certainly helps me take Krita more seriously than GIMP.
Perhaps thanks to this validation, Blender *is* competing successfully against first-mover Autodesk Maya for use in feature films, etc. I'll celebrate that!
For people who care about, support, or build Free, Libre, and Open Source Software (FLOSS).
