As far as I know in the past NIX was aggressively removing upper version constraints, but this seems to have led to problems and they changed policy: http://lists.science.uu.nl/pipermail/nix-dev/2015-January/015608.html Having a set of compatible packages is one of the key Stackage goals https://github.com/fpco/stackage/blob/master/MAINTAINERS.md#adding-a-package If the project takes traction (as it seems) this problem should disappear. I would consider a discrepancy between a cabal file on Hackage and the actual cabal file included in a tar archive a bug. It may be helpful to report it to the author.
