## 💡 Recomendaciones

### Lo Importante Ahora

1. **Publicar service-registry crate** (CRÍTICO)
   - Permite que otros proyectos usen la abstracción
   - Sin esto, el patrón no es reutilizable

2. **Setup central repository** (CRÍTICO)
   - Single source of truth
   - Foundation para todo lo demás

3. **CI/CD validation** (IMPORTANTE)
   - Previene cambios inválidos
   - Protege a todos los proyectos

### Lo Que Puede Esperar

1. **KCL integration** (NICE-TO-HAVE)
   - Útil solo si usas KCL en cluster definitions
   - Bajo ROI si no

2. **Multi-region** (NICE-TO-HAVE)
   - Solo relevante para ciertos use cases
   - Agregar después de completar foundation

3. **ArgoCD/Flux** (IMPORTANTE)
   - GitOps es el futuro
   - Pero puede hacerse después de Fase 2
