I think people overestimate the necessity of 'high level' conveniences or the difficulty of writing C/C++ to the metal.

For example, take Dear.IMGUI which is a c++ UI framework with a kind of data binding, which generates vertex buffers which can be directly uploaded to the GPU and rendered.

It supports most of the fancy layout stuff of CSS afaik (flexbox etc), yet its almost as low level as it gets.

The code is also not that much harder to write than React.
