So yes, you want that. But how about the next question? The dependencies of your dependencies may conflict with different versions of themselves. Because nobody thought 'what happens if there is another version of this code running in a different namespace'. And nobody tested it, so you are trusting to luck rather than any sort of rigor. Thankfully, the conflicts when they happen are usually fairly obvious (two copies of the connection pool built into your database driver, or a crash on startup because the run-once initialization ends up being run twice). But it could be more subtle, like multiple versions of the dependency that handles logging not sharing a mutex and your logs end up interleaved or corrupt under load.
