I think they are waiting for someone else to build for it which is IMO the completely wrong approach for the dream of the serverless app. You got to own the full stack including software.
I can easily see Vercel becoming the pretty much only go-to in this space just from the developer trust they have created with Next (and now Svelte). The general getting started experience between the two serverless providers is night and day.
One is where do I begin / how should I do this (cloudflare).
The other is simply code... and... go! (vercel)
I'll be all in on whatever Rich makes there. Been waiting for a solid Cloudflare Worker framework for literally years bridging front-end and back-end. Instead, we got Pages (which is cool, just boring for the fun stuff).
