You're missing the point. Most software doesn't need to scale or solve hard data storage problems, and if it ends up having to, you can always upgrade to Postgres with minimal effort. That makes SQLite an attractive option if you won't immediately benefit from Postgres' rich features.
We're just going to be speaking past each other, I think. GP clearly stated they lean heavily on Postgres technologies (by calling out specifics like pgvector). Stating that the applications that don't need those technologies, indeed don't need them, is tautological!
