I really like your idea about officially supported packages, but also to group them together for popular techstacks.

This was exactly the same problem I had. There were so many options that just didn't work well that I wasted tons of time trying out every plugin I could find to solve my problems.

And I still didn't fully solve it, I just gave up and lived with annoyances.

Edit: I perceive VScode partially solved this problem with the download count/voting on extensions.
