On a related note, Haskell packages retain needless references to *all*
other Haskell packages at build time. That’s because we *copy* their
.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/<name>.conf.d
directory.
I don’t know if all the files in there are really necessary, but it
seems to me that perhaps this leads to spurious references.
