  # Why do we have splicing and yet do `nativeBuildInputs = with self; ...`?
  #
  # We use `makeScopeWithSplicing` because this should be used for all
  # nested package sets which support cross, so the inner `callPackage` works
  # correctly. But for the inline packages we don't bother to use
  # `callPackage`.
  #
  # We still could have tried to `with` a big spliced packages set, but
  # splicing is jank and causes a number of bootstrapping infinite recursions
  # if one is not careful. Pulling deps out of the right package set directly
  # side-steps splicing entirely and avoids those footguns.
  #
  # For non-bootstrap-critical packages, we might as well use `callPackage` for
  # consistency with everything else, and maybe put in separate files too.
