This is awesome work! The UX benefits of consolidating functionality are real.
Though I have concerns about super apps as a concept - they're kind of an authoritarian's wet dream. We see this in China where they become centralized control points. Even with non-custodial architecture, the more functionality you concentrate, the bigger the target for capture.
The complexity creates maintenance burden that makes it harder to keep things truly decentralized and neutral. More features = more attack surface, more dependencies, more reasons for compromise.
Not a critique of Nostria specifically - clearly valuable work. Just thinking about the broader architectural tradeoffs between super apps versus more composable, specialized tools.
