could not disagree more. That statement alone makes me completely lose any consideration for this entire project.

It never really went away for me. I still reach for it in every web app. Over time, I've stopped using some parts of it that used to be timesavers... e.g. shifting away from $.ajax calls to fetch, but it's a good base for rolling your own responsive frameworks if that's what you want to do. And it's what I want to do, because I dislike the paradigms for react and vue, and have no interest in relying on those projects.
