One of the few decent uses for containers is to enforce proxied internet so build process artifacts can be auto-stored for subsequent builds. For the worst offender I am aware of, try building a flutter project... it silent internet gets artifacts from at least three different packaging systems (node, cocoapods, android packages), all of which have caused hard-to-debug failures.
