In this thread there seems to be no end of comments seeking to tear down the project under consideration.

In my opinion, this project is a good initiative and more folks should take a page from this project's book. Even if you think such a project is critically flawed, an effort to thread a needle and help the community deserves praise and constructive feedback. In this particular case, the author(s?) is apparently taking the time to study a broad selection of UI frameworks and synthesize what they are learning into something everyone can benefit from. That's awesome, and I hope they keep up the good work
