Unfortunately, these bootstrap variants remain in the reference > graph alongside their non-bootstrap counterparts. On a related note, Haskell packages retain needless references to *all* other Haskell packages at build time. That=E2=80=99s because we *copy* the= ir .conf files at build time to create a package cache, and these .conf files thus propagate even to unrelated packages. We are effectively using propagation via the lib/ghc-8.6.5/.conf.d directory. I don=E2=80=99t know if all the files in there are really necessary, but it seems to me that perhaps this leads to spurious references. --=20 Ricardo
