Having to update all clients at the same time when deploying a Wireguard with different ciphers is solvable with just deploying another Wireguard server alongside the new one, right? I mean it's debatable whether one likes this approach better than more complex cipher negotiation protocols -- clearly these things should not be thought about in absolutes or "best practices", but as tradeoffs with different pros and cons. Wireguard seems to prioritize protocol complexity above upgradeability, that's not to say one is better than the other.
