We usually replace plain references to libraries with exact store paths.

This sounds useful, but to me it feels like wrapping executables in
LD_LIBRARY_PATH, which we try hard to avoid.
When using cffi:*foreign-library-directories* how would we deal with
cases where we have more than one package specifying cffi-packages?
Would this option need to be considered for every package in the package
closure? Would it need to be handled by a profile hook in case these
packages are installed?
