We'll see if this improves compile times at all, but I think it's worth doing as at least the most minimal form of module documentation. This was accomplished by first compiling everything with -ddump-minimal-imports, and then a bunch of scripting (with help from ormolu) **EDIT** it doesn't seem to improve CI compile times but the noise floor is high as it looks like we're not caching library dependencies anymore PR-URL: https://github.com/hasura/graphql-engine-mono/pull/2730 GitOrigin-RevId: 667eb8de1e0f1af70420cbec90402922b8b84cb4
