RED Cameras licensed to use the RF mount by Canon as noted in this article, should support RF lens sales.
"Canon wants to sell lenses above all else, so much so that it will let another camera maker — one that it arguably competes with in the cinema space — use its mirrorless lens mount. Since Canon is the only manufacturer that can support RF, any sale of a RED camera means the sale of Canon lenses. That means more money. Seeing Canon block others from making lenses for RF while at the same time licensing it for use by a camera manufacturer only further drives home this strategy." : petapixel
