But it is not a viable choice anymore to “not include this useful dependency, because its dependency tree is huge, so I will just rewrite it from scratch”, which is what practically happens in most cases. No one deliberately imports bullshit like leftpad on the root level. If you use react alone it will probably already make enough of a mess that windows’s file operations will take considerable time on your node_modules folder, which is ridiculous in and of itself.

Nobody is saying "rewrite everything".

We're saying "think about each dependency you're considering pulling in. Maybe have a quick browse through the code. Is it a gigantic hot mess? Is it tiny and elegant? Does it only have 3 downloads/week on npm? There are lots of things you can do before deciding to rewrite it yourself, but yes, I argue there are definitely some dependencies where that is the right call. But also, YMMV - it depends on your team and resources too.

there are room between huge dep tree and rewriting everything, that's where we should aim

for leftpad, even if I know it's just an example, there's a native String#padStart, and else lodash is pretty small, most mainstream libs have few deps actually
