Good thought but I am not sure if OP's examples illustrate his thought well. Same thought, another example: I like React + its ecosystem quite a lot but often, no, actually most of the times, I realize that I don't need React because the project I am just building is more or less kind of a landing page with some simple UI. Then, I rather use Pug (former Jade) + Stylus + Node. Super simple, proven and you can go quite far.
