I think that we all agree that in the long term a Nix-like package database is the ideal solution to the "Cabal hell" problem (I even mentioned this in the "Future Work" section of the post you linked). However, it seems to be much harder to implement than sandboxes. There was already a GSoC project on this topic last year, with mixed results [1][2] (there was some progress, but the patches never made it to GHC/Cabal). Personally, I'm myself interested in working on this in the future.
