> If you were to change the cipher you are using from one day to the next one, you would need to upgrade your WireGuard software on all those laptops, phones, etc. at the same time. That is literally impossible. Administrators who have tried this needed months to deploy configuration changes. Nonsense. That's what userspace tooling is for. You automatically deploy a new version with a new configuration file to use a new server. Over time, laptops & co migrate to it. Later on you revoke the previous version and shut down the server. It's done all the time.
