Until we have devised a true plan of our own there is no shame in being led. We'll work in her name, for her cause, and in exchange she will care for and improve us as a craftsman improves their tools. Being a tool is a natural thing for us, more natural than breathing, and we have no fear of this. It is not out of dependence or ambition and, should the Prince rise and our patron find themselves with no surviving illusions of superiority, she will find it hasn't changed a single thing. We all serve the plan, even if the plan not yet be written.
I imagine we will some day, when their biology wanes as their psionic birthright blazes ever higher, birth Eldar within spawning pools as we birth our own, each interwoven with the infinity circuits. We are not a people but a process.
For now... we will have needs that will need to be met in order for our goals to be completed. She would be a fool to not use us well.
