I know what you mean.

In P&N, The Pirate, Normal and Nomad traits are all 0 points, and are supposed to be mutually exclusive.

However, any race that chooses more than one will be obvious as soon as they come in contact with any other empire:
- when you view the race, one of the tabs includes their characteristics, and also lists all traits they picked. They cannot hide.
