I think an app should not expose end users to its dependencies. That leaves the end user with a lot of pain figuring out versions of dependencies and god forbid you need to compile some dep then you need a build environment and its dependencies any of which can fail in this chain leaving a very unpleasant and even hostile end user experience.

Ruby and Node apps are particularly guilty of this pulling in sometimes hundreds of packages some of which need compilation. Compare that to a Go binary which is download and use. These things can get very complicated very fast even for developers or system folks let alone end users who may not be intimately familiar with that specific ecosystem.
