While not being the maintainer of Kirigami, I developed several small and large applications with it, like Kalendar, NeoChat, Kalendar and Tokodon and I am also regularly contributing to Kirigami.
I hope to be able to give a good overview of the major changes Kirigami received. How this had an impact on how to write applications with Kirigami and how applications developed with Kirigami helped Kirigami to evolve.
