Not all Haskell packages (those in hackage.org) are in the stackage snapshots. Stackage is opt-in, there must be a maintainer willing to resolve the occasional build failures. That means there is no such thing as 'too big', because the number of all existing packages in a ecosystem doesn't matter. It's the commitment that counts, and that's what I don't see in the JS community.
