No, but think about the trajectory. Most people new to building a frontend bare-prompt. There's value for them in using the most supported language, including support from AI systems.
To me, it looks like this new project is aimed more at being able to develop remotely and share your localhost:3000 env instead of getting a real production box up. Bidi sync etc... hints at that, it's like having a 2-interface dev env.
The network effect gets compounded by LLMs/vibecoding. I'm not just talking about v0 or replit either. Fire a prompt at ChatGPT to build a web app and most of the time it will give you react components in return.
