[WH40K] Would the Emperor accept a slave race purely devoted to its master?

Lets say that the Emperor finds a slave race that had been idle after they lost thier masters. They became fanatically devoted to Humans after they find them and would take all the abuse even at the risk of death just so they can serve. The way they serve conforms to the ideal servant for Humanity and have proven themselves to be quite devoted.

Would this appeal to the ideal of the Emperor of a Xeno race thats not a threat to humanity or would the Emperor feel be a threatend by their devotedness?

Absolutely not. 

That basically screams trap and goes counter to the idea that humans only need humans to survive. 

We would never turn over any modicum of power to a xeno no matter how small or trivial. 

Only possible scenario is to use them as canon fodder until they are extinct. Even then there would have to be extenuating circumstances to even entertain that idea.
