Well, given that the government type should probably never be mentioned in a short name, I'd think that was a good reason on its own.
I believe Tim mentioned that there is a filter to disallow using government styles in the realm name. i.e. You aren't supposed to be able to name your realm "Kepler Republic". The Farronite Republic slipped through because the ruler who formed the realm typo'd the name. Tim fixed it for them.
