Well, this is designing brand-new error reporting channel to the
userspace. I see that changing dmesg to provide something usable for
gettext would be hard, but it is quite trivial to do it right this
time.
I agree we survived without that for a long time, but we have chance
to do it right for a minimum price (because the interface is new we
don't need compatibility).
