The 'Realm of __' is not the only tag that a nation can have. There are 5 others and they are similar to the town tags (Village, Metropolis, etc.) in which one you have depends on how many total residents there are in your nation. Most nations will have the Realm tag because you need 60+ residents to get it, which isn't very hard for a nation.
it would be a waste of code to remove it

I agree with this, I would rather have the techs focus on more important things, however on trello there is a list of improvements that can be made to nations (

My personal thoughts on this suggestion is that we don't remove the nation tags altogether, but simply format them in the same way as towns, eg. TownName (Tag). This way, The Taurus Realm would be changed to Taurus (Realm). I also think that the residents required for each tag should be greatly increased (same with towns). Getting a new tag is something that nations and towns should work towards, not be able to get instantly (I might suggest this later).
