I agree that react/vue/etc. aren't necessary, however this approach is not diametrically opposed to using a JS framework.

For example, if you use a framework like Stencil or Next.js w/ React, you will be able to pre-render your page into static HTML to serve to clients, but you also get the benefit of having rich JS components and code sharing. And then you avoid a lot of the issues they seem to have around lack of DOM diffing and the like.
