I thought I could stay within Cabal without adding Nix, however Nix
was on my mind.

My initial thought is: for bootstrapping, I could dump package
descriptions from the global database for few basic packages (rts,
ghc-prim, base, etc.) and run them through ghc-pkg register with
GHC_PACKAGE_PATH set to cover only per-project package conf directory.
