That was the conclusion then, but it was incorrect. Real HW works like that, but qemu_irq only handles transition edges. It does not have state.
A hardware irq line does not have state either. It's a means of exposing state within a device to somewhere else. On reset, the device internal state changes, and the qemu_irq must reflect that change.
Internal muxes like the shared-line OR gates don't have state; they can always be recomputed from their inputs.
