Cargo is best there is in this domain so far. Poetry is good. I rarely use anything else. Important things: 1. Consider what developer need and what devops need. Those are different needs. 2. Packages should be immutable. 3. Take care about what text you print. This should be to the point, no spamming. 4. Having reliable package repository is the best way to go. Getting dependencies from random git repos is a recipe for production issues, as those come and go. (I do not now Rel, so maybe this is irrelevant).
