2. A converter still means maintaining two model systems. The point was to not have two in the first place.
3. MessagePack overhead is negligible compared to actual DB round-trips. And the Rust core isn't just SQL generation, it bundles the full driver stack (sqlx), pooling, and streaming, so you don't need asyncpg/aiosqlite as separate dependencies.
