Re: From a user's point of view...
Strict naming conventions can be both a help an a hindrance. Automation loves it, up until it breaks.
However, these people do have an option available to them, the same one as my ex-wife took. Her employer insisted that their legal name be used on all official communications. Her given name was Christine, her grandmother's name, which she always felt was stuffy and old fashioned. Everyone called her Chrissy, but work wouldn't allow it... Until she changed her name by deed poll.
If you really hate your name, that's the best option. If you just dislike it and don't want the hassle, suck it up.
