The technical merits of v9 cannot be dismissed. Several low-level enhancements directly address long-standing pain points: faster startup times, better memory footprints, and native hooks that make integration with modern cloud-native tools less clumsy. When milliseconds matter—serverless functions, auto-scaling microservices—those wins translate into real cost savings. Moreover, improvements in the tooling chain reduce the friction of modern development workflows and make refactoring less risky.
