Exactly. It is actually impractical for the Imperium to make Chapters individually or in small groups due to the logistics required to do so. That is why Foundings make large numbers of Chapters. Curonis simply wouldn't have the resources or the ability to coordinate in order to perform a founding. Not even one where only a fee Warbands are created.
