No disagreement on that point. I am talking about new and maintenance projects. My pet peeve is "just install this, just use that, oh and by the way also definitely install this" for things that should either be built-in, or well-standardized (minifiers, tree-shaking, transpiling). And they are not.

If I get into a new team and there are 3 devs already writing JS, it's highly unproductive because it feels like you have to very regularly catch up with the JS ecosystem. Not to mention the strong peer-pressure factor of "cool kids use X, Y or Z". And this is a very underestimated phenomena by so many devs -- and it exists in almost every team.
