React falters because there are not many community contributing towards react integration.
Note: Vite team has done their job for react, but react itself has many concerns particularly due to commonjs that a dedicated person (or team) is needed for react
This is like saying NPM is language agnostic. Sure, technically it is. But we all know what it was built for and what the community is geared toward.
Angular is the same way, it has its own compiler and relies on custom build-time code to work. That's also why it isn't picked up by a lot of newer build tools that generally just work with normal JS.
(With that said, I'd love to see Next use Vite, but iirc the webpack dev works for Vercel [Nextjs parent] now)

When there is ssr, there is runtime, more than just a dev/build tool.
That does not seem to be the truth. They offer a very different product than Next.
