Disable "shadowed dependencies" workaround when GHC is new enough #3554
Description
This is a task for a release of GHC beyond 8.2.2. Here's what's going on:
-
There is a bug with ghc-pkg, see Shadowed dependencies during builds with Cabal 2.0 WAS: cabal 2.0 and alex on macos haskell/cabal#4728
-
There is a patch on phabricator that will hopefully land after 8.2.2: https://phabricator.haskell.org/D4159
-
Reconfigure is currently forced when deps are rebuilt - Force reconfigure when deps are rebuilt #2781 #3503
So, this issue is tracking disabling the reconfigure workaround when upstream is fixed, as this will make builds faster.
