There are various reasons for this; since this bug report is about Stackage curation, the reason we have is to avoid having to manually match the Cabal library and cabal-install versions.\r\n\r\n@bgamari asked me to run the latest GHC 8 release candidate through the Stackage gauntlet. Unfortunately, due to the lack of `--allow-newer`, it's quite difficult to do a proper test of GHC 8, which includes a new version of many core libraries. My ultimate workaround is quite ugly: [rewriting the .cabal file with all version bounds stripped out](https://github.com/fpco/stackage-curator/blob/69b15c2c7fb2d4dfba286b1348d8f8c72efa00ce/Stackage/PerformBuild.hs#L773).\r\n\r\nFor the record, all of this GHC release candidate testing is in the repo https://github.com/fpco/ghc-rc-stackage, which is just a Dockerfile, shell script, and some docs."}}
