The project is still in active development. Although already used in pilot projects, it's not suitable for all production scenarios yet. Being developed by only one person, it may keep going for years or stop at any time. In the meantime, it's still a "research project" that needs improvement. Thus, it will be subject to BREAKING CHANGES as long as the version is not 1.0.0. All that said, the end goal is really to have a production-grade library to help everyone build quality projects faster. If you want to help in any way or have questions, feel free to contact me (cf. author in package.json).
At the beginning, the whole documentation will be on GitHub, starting from this file, to make it easier to have the big picture, maintain and cmd + F. At some point, I'll consider having a beautiful documentation website like all the cool kids.
One might argue that, with so many "JS frameworks" on the market, there are already too many ways to build new applications today. And they would be right.
