Ever wondered whether wrapping simple IDs in opaque types is overkill? My take walks through TypeScript and Rust examples, ties wrapper types to Domain-Driven Design and primitive obsession, and I argue how an opaque UserId type and ownership cut bugs even in pass-through services. Includes code sketches and trade offs.
Rolly's Take
