How to reduce the weight of compiled Haskell code?

Answer 1

GHC option -split-sections
But it must be included on the entire codebase and all dependencies, otherwise it will cut one package, and the rest of the world will stick entirely.
cabal-install, globally in `~/.cabal/config`:
split-sections: true
stack, in each project, in `stack.yaml`:

ghc-options:
  "$everything": -split-sections
