There is no appstream metainfo file installed (so far, I noticed that upstream ships one so I'll install it in the future). Finding that out was quite a huge digging around, it's not well documented or visible.
The package though is in Debian main/Ubuntu Universe, and thus implicitly is clearly free software. So the software center not recognising those sections seems to be a flaw in the way the software center tags packages where it can't find a metainfo file.
