Depends. If I feel it adds an interesting flavor to the game I'll add equipment that was used in as small numbers as 1 or 2. If it offers no real difference from existing units then I wouldn't bother. Really, if I want to do very rare variants or pieces of equipment I make good use of the X3 radio code with a text note for the unit in the encyclopedia or create a whole new formation and reclass the unit, along with both encyclopedia and formation text.
