Well, there are 3 cases: - "usual" case (if you agree): dependencies will be downloaded from the Internet, single command download+build is useful - in a bank/SC environment: the developer configured a proxy/local mirror of the package repositories, and the dependencies will be downloaded automatically, single command download+build is useful - in a bank/SC environment: manual process to obtain and add locally the dependencies, the build/dev system has limited networking: automatically download fails, single command download+build is not useful but not harmful either Having a "prefetch" and "offline-build" commands are perfectly fine, but I don't see the reason why the default shouldn't be a "build" command that does prefetch+offline-build
