This is funny, yes. It seems intentional, though:

  https://sources.debian.org/src/util-linux/2.38.1-5/sys-utils/dmesg.c/#L1505

calls parse_level with a second arg of 0, which causes parse_level()

  https://sources.debian.org/src/util-linux/2.38.1-5/sys-utils/dmesg.c/#L348

to add an offset of 1. No idea what the thought behind this is.

Perhaps backward-compat to some forgotten lore?
