Top-level error handling doesn't mean losing error details. When done well, it uses specialized exceptions and a catch–wrap–rethrow strategy to preserve stack traces and add context. Centralizing errors provides consistency, ensures all failures pass through a common pipeline for logging or user messaging, and makes policies easier to evolve without scattering handling logic across the codebase. Domain-level error modeling is still valuable where precision matters, but robust top-level handling complements it by catching the unexpected and reducing unhandled failures, striking a balance between developer effort and user experience.

If you are actually using specialized exceptions and a catch-wrap-rethrow strategy then you are doing error modeling and you aren't "Just letting them bubble up to the top" which is basically making my point for me.
