I think it is relevant, it's a part of the standard library. It's one problem that JS has one of the smallest standard libraries, and it's another that the parts it does have just... don't work.

And, "don't use the standard library" is not a solution. Well I mean it is, but it's not free - there's caveats. Which tools do you choose? How do you make sure all your engineers use the same ones? How do you make sure nobody touches the standard library? It's not an easy problem.
