Anyone who feels compelled to jump from one unproven state management library or bundler to another, in serious projects, is just not doing their due diligence.
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.
Not OP. At a big tech company. As far as I can tell neither myself nor anyone I work with has touched a system developed in the past 6 years that didn't use React with with Webpack and/or Esbuild for the build system. Of those, 90% + used Redux for state management or switched to Redux after starting with a different state management system like mobx or xstate. The only exception to this the only exceptions are apps that needed something Recoil-like (e.g. Redux caused too much computational overhead). Some of them also used Nextjs for static pages.
