Sigh, it looks like my post was half or a quarter read. The minor xenos races (without humanity) would be wiped out by more dangerous and larger xenos races (such as Orks or Dark Eldar) whom focused on attacking humanity. And furthermore, these minor xenos races would have extreme trouble becoming as large as the Imperium or even the Tau Empire. Humanity and the Tau had legendary and wise leaders guiding them to be a galactic imperial power, 1 out of 100 minor xenos races would atleast become as large to cover one or two star systems. If you were to say that Humanity is the main reason these minor xenos species are suppresed, then you'd also have to assume the Orks, Dark Eldar, Necrons, Tyranids, and other aggresive xenos are all innocent, cute, doves who would never hurt any race!

Half of the major xenos species that inhabit the galaxy are enemies of Chaos and will stop minor xenos species from propagating to feed the Chaos Gods, and they themselves are unable to directly turn to Chaos. (It feeds a Chaos God when a certain event pretaining to a specific Chaos God occurs, I.E a disease infects a planet or a war occurs, but it feeds a Chaos God double when one of their followers, which are mostly humans commit these acts, which is why Chaos rewards a certain individual). We also have to remember that the majority of the minor xenos species would likely be hard for Chaos to recruit, ether due to a lack of psykers, or a devotion to a specific cause of order.

The Chaos Gods are not the C'tan, Chaos must feast on the galaxy every minute of it's existance. And if the feast is not as bountiful as it could be, then Chaos will weaken. And if Humanity was not there to feed or serve Chaos, then Chaos Gods (Other than Slaanesh) would slowly starve. Furthermore, it's usually Human sorcerors that use sorcery to open up portals for Daemons, without these large numbers of Human sorcerors, daemons would be mostly unable to spill out and conquer realspace. As I've said before, Chaos would never want Humanity extinct. Chaos loves it as much as it hates it, Mr. Imperator fought Chaos to protect Humanity for that reason, else, he would have simply protected the entire galaxy; including xenos species if they are so vunerable to Chaos.

Sure other xenos species would rise eventually if Humanity goes extinct. But eventually the Eldar would also go extinct, and since both the Eldar and Humanity are the prime feasts for Chaos, both being extinct would spell disaster for the Dark Gods. Slaanesh might barely drag on alive (since some minor xenos species worshiped Slaanesh), the other Chaos Gods would mostly die out, Nurgle would be unable to take advantage of weak human immune systems, Tzeentch would be unable to grow in power from the great amount of Human psykers who desire knowledge, Khorne would starve since the majority of galactic slaughter is conducted by Humanity or on Humanity. And the Chaos Gods certainly aren't going to commit suicide by killing off Humanity before it could grow.
