-- Plugin flags are designed for 'cabal install haskell-language-server':
-- - Bulk flags should be default:False
-- - Individual flags should be default:True

-- The intent of this flag is being able to keep the ghc condition for hackage
-- but skip it via flags in cabal.project as plugins for new ghcs usually
-- are buildable using cabal.project tweaks
