Interesting, though I wish it also supported functions that return a promise... in this way, the resolve action could be the positive result for the worker, and reject could serve as the error result... in this way, async functions could be used.
While I agree with the sentiment... at this point the web development community is already very fractured. Angular is still very strong in new business development, and React is just starting to edge in. I'm not suggesting that we stop, but there is merit in sticking with React+Redux for a while.
In terms of features, universal rendering, and hot module replacement are important for iterative development. React+Redux is at the leading edge of these features, well ahead of many alternatives. Once the tooling for other options matures, I think it may be worth considering... for now, I'm a cautiously optimistic observer.
I will say there have been far fewer surprises with React+Redux than there have been with options that came before. I don't mind OO syntax for components, but find that workflows work better in a more functional style. It just depends on your needs.
Regarding babel 6, most new browsers support most features that required transpilation in the box, beyond that, many can be polyfilled dynamically such as via polyfill.io ...
With that in place, you may not need to enable many ES6/7 features within your bundles/code. This reduces the load of your application on a client computer. No need to load code on a client that isn't needed there.
That's the main motivation of babel changing strategies, there have been a lot of requests to have specific packages for different targets... by breaking out the options and targets it allows you to have more options available.
I didn't really read the rest of the rant as many enterprise applications have pre-requisites... setup your database, etc... most npm apps are npm i -g appname, or when you clone from github, npm install... also requiring an appropriate version of node. Having dockerfile available in the projects helps too.
