Comment 5 for bug 1744318

I think I vaguely recall some issues that occured after this SRU in bionic, but I'm not sure anymore. It certainly means that tools stop working for people behind proxies in quite a few cases (e.g. various apt proxies not allowing https connect; or access to changelogs.ubuntu.com).

So we need to consider whether the benefits of backporting this to xenial outweight the risks.
