> Rust (and really, any but JS) ecosystem have a bit more "due dilligence" applied everywhere; I don't doubt someone will try to namesquat but chance of success are far smaller

I really agree, and I feel like it's a culture difference. Javascript was (and remains) an appealing programming language for tinkerers and hobbyists, people who don't really have a lot of engineering experience. Node and npm rose to prominence as a wild west with lots of new developers unfamiliar with good practices, stuck with a programming environment that had few "batteries included," and at a time when supply chain attacks weren't yet on everybody's minds. The barriers to entry were low and, well, the ecosystem sort of reflected that. You can't wash that legacy away overnight.

Rust in contrast attracts a different audience because of the language's own design objectives.

Obviously none of this makes it immune, and you can YOLO install random dependencies in any programming language, but I don't think any language is ever going to suffer from this in quite the same way and to the same extent that JS has simply due to when and how the ecosystem evolved.

And really, even JS today is not JS of yesteryear. Sure there are lots of bad actors and these bad NPM packages sneak in, but also... how widely are all of them used? The maturation of and standardization on certain "batteries included" frameworks rather than ad hoc piecing stuff together has reduced the liklihood of going astray.
