Build tool complexity is what I dislike - it's certainly possible, but the trend I dislike is build tooling increasing complexity of the build system of the frontend, decreasing accessibility for onboarding developers. JSX is an unnecessary offender in this department, bringing us farther away from plain HTML.

Have you seen Webpack (https://webpack.github.io/)? It's a very powerful tool, but it's quite simple to start with. I can recommend this tutorial: https://webpack.github.io/

Ha, I just realized I posted the same link twice. This is the link to the tutorial: https://github.com/petehunt/webpack-howto

Why use JSX at all, then?

    var d = React.DOM;
    d.div(null, 'Hello', d.strong(null, 'World'))
