These pose a risk to the stability/reproducibility of the app if their dependency graph includes dependencies that are not locked down to a git ref, as per https://github.com/subugoe/muggle/issues/184.
This has broken our builds sometimes in the past.

We should avoid by using CRAN versions in production as much as possible.
We can use our "own" dev versions (such as biblids), where we can, in turn, lock down dependencies hard.
