Well, I am not sure to understand the question.  Basically, Julia
packages require run-time packages and, except very rare cases, we need
to specify them via propagated-inputs.  The the packages required for
running tests are listed with native-inputs.

For instance, consider the package julia-tables, it reads:

    (propagated-inputs
     (list julia-dataapi
           julia-datavalueinterfaces
           julia-iteratorinterfaceextensions
           julia-tabletraits))
    (native-inputs
     (list julia-datavalues
           julia-queryoperators))

when Project.toml reads

Obviously, you need to maintain a hard-coded list of built-in Julia
packages as LinearAlgebra, OrderedCollections or Test.

Does it make sense for your question?
