Another way of things changing:  Some Imperial guardsmen, tired of being treated like cannon fodder, and the xenophobia that drove the Imperium to use them this way, bails and hides out one a planet the Imperium has forgotten. They run into some Tau who have concluded that the Greater Good sucks. It takes a while, but they decide to put aside their differences. Some Eldar come across them and decide that it's time to stop being arrogrant pricks and start lending a hand.

The resulting Confederacy decides to hunker down in some space that nobody else wants. The spend most of their time arranging for the other faction to face each other.
