This naming was once introduced for the ARM PB11MPCore
that had two cascaded GICs (commit 58b8964990dc6)
so it became a pain to see which one
was being used in /proc/interrupts
arch/arm/boot/dts/arm-realview-pb11mp.dts

I see it is not appreciated to use /proc/interrupts for this
type of diagnostics. Ugh. I suppose people do it for the
same reason they keep using the GPIO sysfs, they like
it and they know it.
