Security systems need to work for everyone not just you. The more "special cases" the weaker the security is.
Oh, and if it breaks the database, that's your problem.
If renaming a server is not easily fixed by a config change then whoever wrote the system is an idiot. Sorry but we can't deal with your and the other 20 naming schemes that individuals though were "cool".
We just patched all the servers for greater security. Too bad you can't use your software to control or monitor them anymore, but that's your problem.
If you are relying on a outdated control or monitoring software it is your problem. Your software may even be using the security flaw.
Due to a breach, everyone must change their password. Too bad it happened while you were off for a few days and needed to log in for an emergency, but that's your problem.
This is exactly the same as a person forgetting their password in an emergency situation. If your system can't handle it then it is your problem. Should we leave the leaked credentials valid till we contact everyone in the database? Even those on holidays who might be unreachable?
