Well, the development process is just that: one of development. In this case BI went through quite an intense phase of having ideas considered, reworked and disgarded. At one point we considered having more emergent factions, at another we briefly thought about allowing the player to swap factions when an emergent one came out. Both of these ideas were eventually dropped. This sort of thing happens all the time, because "no plan survives contact with the enemy".
And then material tends to get left in folders. Like junk DNA, it doesn't do anything, but it provides a record of the evolutionary process.
