This has nothing to do with build process, this has everything to do with the expectation that a project will continue to exist and put out new releases. All out builds at work, in fact, are offline. We check in tarballs and we don't access the internet. That has nothing to do with whether I can tell my boss in good faith, allow me to submit a patch upstream and it'll be worthwhile to the company and we won't have to carry local patches. Right now I can say that. Why would we want to get rid of that?
