This is the reason I wrote "bash-drop-network-access" [0]. I use it as part of my package building system so that downloads are only done in the "download" phase of building where I validate and cache all objects. This means I can fully verify that I can build the whole thing air-gapped and far into the future with the set of files identified by the SHA256 in each package's buildinfo.
This is important because I support each release of the distribution for up to 10 years, and have some customers who may need to build it in an air-gapped environment.
