By testing line-by-line in this way, any change to the dependencies of these libraries becomes breaking. If we check all lines instead, new dependencies won't break these tests.
I have verified that this change actually fixes the spurious CI errors by adding a test commit to that PR, bumping Pkg.version to this commit, and checking the CI output (no more Pkg errors).
