twig / circle integration
If this ever becomes a software centre designed around GNOME™ as a platform rather than something tailored around the needs of umpteen different distros then it might make sense to offer a mechanism for notifying the user of news and updates to the platform itself along with apps which are part of circle ( TWIG seems like a good candidate ). You could imagine taking it further and including a link to e.g mastodon account in appstream metadata in future for allowing app developers to integrate with the software centre in a similar way to how its done on lets say steam.
This could be a good way of widening the net through the opt in contribution towards user studies for scenarios where privacy-preserving telemetry is a hard no from some users whilst opt in user studies are considered perfectly acceptable to them.
