For example, Cloudflare released their vite plugin which makes it effortless for frameworks that use the vite env API to run inside workerd (meaning you get to use cloudflare service bindings in dev) back in April and only React Router had support for it. Nextjs has no support, the draft PR to add support for Sveltekit has been parked until the next major version, Astro only just added support in their beta 6.0 release 3 days ago
With this acquisition, Astro will probably be first to future updates that increase compatibility with cloudflare. It's smart, and was probably not very expensive (more of an acqui-hire)
