Hasn't changed since I last looked at it. Still a big clusterfuck of esoteric math libraries, wrappers for useful things written in other (practical) languages, and a handful of half finished clones of libraries and applications first written 10 or 20 years ago in C.
This is a bit unfair. Every code repository has this sort of thing. The quality of a repository shouldn't be the ratio of [no-external-dependency + extremely mature] projects, but rather should be based on whether or not people can find what they need there. I'd argue that Hackage has that.
As for being full of bindings to languages written in other libraries, why is that a bad thing? In general, these libraries are common, cross platform, and thoroughly tested. Isn't code-reuse worth something?
