What out-of-the-box Angular features require manual setup in Vue or Svelte?

This tests whether you understand framework scope tradeoffs and first-party versus ecosystem distinctions. A strong answer lists Angular's router, reactive forms, dependency injection, and Signals, then notes that Vue and Svelte typically rely on official but separate packages like Vue Router or SvelteKit for routing, plus community libraries for complex form handling. Red flag: claiming Angular is better without acknowledging that smaller bundles and explicit opt-in choices are genuine advantages for other frameworks.
