> I've used the same React tech as the basis for most projects for 6 years now. Webpack, Redux, Yarn, React Router, all still popular and maintained. We even used hooks for functional components since then, through the "recompose" library, so there wasn't a big paradigm shift for us.

Have you worked at different companies or contributed to different OSS projects in those 6 years? If you have, and they've all been set up exactly the same as what you mentioned, that's rare, but great. I think most people's qualms on the amount of different frontend tooling is based on the fact that almost every company or OSS maintainer takes different approaches to accomplish essentially the same thing.
