The pseries machine only uses LSIs to support legacy PCI devices. Every PHB claims 4 LSIs at realize time. When using in-kernel XICS (or upcoming in-kernel XIVE), QEMU synchronizes the state of all irqs, including these LSIs, later on at machine reset. In order to support PHB hotplug, we need a way to tell KVM about the LSIs that doesn't require a machine reset. An easy way to do that is to always inform KVM when an interrupt is claimed, which really isn't a performance path.
