Not in the same sense. An analogy might be: apt is like fetching a git repo in which all the packages are submodules, so lazily fetched. Some of the package managers in the article seem to be using a monorepo for all packages - including the content. Others seem to have different issues - go wasn't including enough information in the top level, so all the submodules had to be fetched anyway. vcpkg was doing something with tree hashes which meant they weren't really addressible.
