The technical approach here is solid. Fine-grained dependency tracking with automatic invalidation is the right way to do incremental compilation. The Rust implementation means it can actually handle large codebases without the JS runtime becoming the bottleneck.

But the skepticism in this thread about ecosystem fragmentation is valid. Vite won because it worked with the existing ecosystem, not against it. Turbopack requiring Rust for plugins limits who can extend it.

That said, if you're already locked into Next.js, this is a clear win. The question is whether Next.js's market position justifies a separate build tool or whether this accelerates the trend of frameworks becoming walled gardens.

I personally love Vite and Remix.
