In many cases, one prefers to have e.g. the NumLock on by default.  In
many cases, one doesn't want to have it by default, e.g. on laptops.

Distributions actually have a very hard time trying to set this
correctly after the kernel boot, and that doesn't work for new consoles
that are created via the openvt(1) command anyway. This hence adds a
keyboard.default_leds boot parameter that permits to configure the
default keyboard LEDs.

Actually, what would be perfect would be to use the configuration that
the BIOS sets at boot by default.  That is device-dependent, however.
